Title
proc: fix UAF in proc_get_inode()
Summary
In the Linux kernel, the following vulnerability has been resolved:
proc: fix UAF in proc_get_inode()
Fix race between rmmod and /proc/XXX's inode instantiation.
The bug is that pde->proc_ops don't belong to /proc, it belongs to a
module, therefore dereferencing it after /proc entry has been registered
is a bug unless use_pde/unuse_pde() pair has been used.
use_pde/unuse_pde can be avoided (2 atomic ops!) because pde->proc_ops
never changes so information necessary for inode instantiation can be
saved _before_ proc_register() in PDE itself and used later, avoiding
pde->proc_ops->... dereference.
rmmod lookup
sys_delete_module
proc_lookup_de
pde_get(de);
proc_get_inode(dir->i_sb, de);
mod->exit()
proc_remove
remove_proc_subtree
proc_entry_rundown(de);
free_module(mod);
if (S_ISREG(inode->i_mode))
if (de->proc_ops->proc_read_iter)
--> As module is already freed, will trigger UAF

No network protocol handling is involved.\nAC:L - The attacker fully controls their side of the race and can hold the window open continuously \u2014 `/proc/net` entries use `proc_net_dentry_ops` whose `.d_revalidate` always returns 0, so every single access re-runs `proc_lookup_de()`/`proc_get_inode()`, and fresh procfs mounts or netns via `unshare -Ur` defeat any dcache caching. On the realistic deployment targets (Android, embedded, automotive) module load/unload cycles are frequent and user-inducible via device/radio state changes, so no condition requires attacker-unattainable luck.\nPR:L - Triggering the vulnerable dereference requires only the ability to look up a path under /proc, which is mode 0555 and open to any unprivileged local user; no capability is checked anywhere on the lookup path. Unprivileged users can additionally use user namespaces to obtain fresh procfs/netns instances and to autoload modules that register `/proc/net` entries.\nUI:N - The attacker\u0027s exploitation loop is entirely self-driven \u2014 a continuous stat() loop on the target /proc entry \u2014 and requires no victim to open a file, mount a filesystem, or otherwise participate.\nS:U - The use-after-free occurs in kernel memory and its consequences are confined to the kernel\u0027s own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a use-after-free on freed module memory; once the vmalloc/execmem region is reclaimed and re-populated (e.g. by a subsequent module load), the stale read feeds attacker-influenceable data into inode setup, and UAF primitives of this class are leveraged for kernel memory disclosure.\nI:H - The UAF causes the kernel to select `i_fop` based on freed, potentially reallocated memory, yielding a stale-object/type-confusion condition on the instantiated inode; use-after-free on kernel structures is exploitable via heap grooming for control-flow-relevant corruption.\nA:H - The commit documents an unrecoverable oops \u2014 \"BUG: unable to handle page fault for address: fffffbfff80a702b \u2026 Oops: 0000 [#1] PREEMPT SMP KASAN PTI\" at `proc_get_inode+0x302` \u2014 and the attacker can retrigger it at will with a stat() loop, causing kernel crash/denial of service."

Title
proc: use the same treatment to check proc_lseek as ones for proc_read_iter et.al
Summary
In the Linux kernel, the following vulnerability has been resolved:
proc: use the same treatment to check proc_lseek as ones for proc_read_iter et.al
Check pde->proc_ops->proc_lseek directly may cause UAF in rmmod scenario.
It's a gap in proc_reg_open() after commit 654b33ada4ab("proc: fix UAF in
proc_get_inode()"). Followed by AI Viro's suggestion, fix it in same
manner.

Title
net/sched: Make cake_enqueue return NET_XMIT_CN when past buffer_limit
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: Make cake_enqueue return NET_XMIT_CN when past buffer_limit
The following setup can trigger a WARNING in htb_activate due to
the condition: !cl->leaf.q->q.qlen
tc qdisc del dev lo root
tc qdisc add dev lo root handle 1: htb default 1
tc class add dev lo parent 1: classid 1:1 \
htb rate 64bit
tc qdisc add dev lo parent 1:1 handle f: \
cake memlimit 1b
ping -I lo -f -c1 -s64 -W0.001 127.0.0.1
This is because the low memlimit leads to a low buffer_limit, which
causes packet dropping. However, cake_enqueue still returns
NET_XMIT_SUCCESS, causing htb_enqueue to call htb_activate with an
empty child qdisc. We should return NET_XMIT_CN when packets are
dropped from the same tin and flow.
I do not believe return value of NET_XMIT_CN is necessary for packet
drops in the case of ack filtering, as that is meant to optimize
performance, not to signal congestion.

Bluetooth: MGMT: Fix possible UAFs
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: Fix possible UAFs
This attemps to fix possible UAFs caused by struct mgmt_pending being
freed while still being processed like in the following trace, in order
to fix mgmt_pending_valid is introduce and use to check if the
mgmt_pending hasn't been removed from the pending list, on the complete
callbacks it is used to check and in addtion remove the cmd from the list
while holding mgmt_pending_lock to avoid TOCTOU problems since if the cmd
is left on the list it can still be accessed and freed.

Title
ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattr
Summary
In the Linux kernel, the following vulnerability has been resolved:
ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattr
Currently when both IMA and EVM are in fix mode, the IMA signature will
be reset to IMA hash if a program first stores IMA signature in
security.ima and then writes/removes some other security xattr for the
file.
For example, on Fedora, after booting the kernel with "ima_appraise=fix
evm=fix ima_policy=appraise_tcb" and installing rpm-plugin-ima,
installing/reinstalling a package will not make good reference IMA
signature generated. Instead IMA hash is generated,
# getfattr -m - -d -e hex /usr/bin/bash
# file: usr/bin/bash
security.ima=0x0404...
This happens because when setting security.selinux, the IMA_DIGSIG flag
that had been set early was cleared. As a result, IMA hash is generated
when the file is closed.
Similarly, IMA signature can be cleared on file close after removing
security xattr like security.evm or setting/removing ACL.
Prevent replacing the IMA file signature with a file hash, by preventing
the IMA_DIGSIG flag from being reset.
Here's a minimal C reproducer which sets security.selinux as the last
step which can also replaced by removing security.evm or setting ACL,
#include <stdio.h>
#include <sys/xattr.h>
#include <fcntl.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>

No network, adjacent-network, or physical path reaches the IMA appraisal hooks.\nAC:L - The commit ships a deterministic reproducer: setting any EVM-protected xattr or a POSIX ACL unconditionally clears IMA_DIGSIG every time, with no memory-layout or timing luck involved. The enforce-mode variant needs a race against `process_measurement()`\u0027s `MAY_WRITE` check, but `ima_reset_appraise_flags()` takes no `iint-\u003emutex`, and the attacker drives both sides (one thread spinning on `setxattr(\"system.posix_acl_access\")`, another on `open(O_WRONLY)`); the required IMA-appraise + EVM configuration is a shipped, supported Fedora/RHEL setup, not a rare build option.\nPR:L - `vfs_set_acl()` invokes `security_inode_set_acl()` \u2192 `ima_inode_set_acl()` \u2192 `ima_reset_appraise_flags(inode, 0)` before `set_posix_acl()` ever reaches its `inode_owner_or_capable()` check, so an unprivileged user with no capabilities and no ownership of the file clears the cached IMA_DIGSIG bit on any signed appraised binary \u2014 the syscall fails with -EPERM only after the flag is already gone. No CAP_SYS_ADMIN is needed for this path, unlike the `security.ima` path guarded by `ima_protect_xattr()`.\nUI:N - The attacker performs the xattr/ACL operation and the file open/close entirely from their own process; no victim must mount a filesystem, open a file, or take any other action for the IMA_DIGSIG flag to be cleared and the signature to be replaced.\nS:U - The defeated control (IMA appraisal) and the affected resources (files and their security xattrs) live in the same kernel security authority; no VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Clearing IMA_DIGSIG both drops the \"signed files cannot be opened for write\" enforcement at `ima_main.c:472` and lets `ima_update_xattr()` re-bless the modified content with a fresh hash plus EVM HMAC, so attacker-substituted content in an appraised executable passes appraisal and subsequently runs \u2014 typically in a privileged/service context \u2014 yielding full disclosure of data reachable by that code. This is the standard treatment of a code-integrity/signature-verification bypass; the bug itself contains no direct memory-read primitive.\nI:H - The file\u0027s IMA digital signature \u2014 the one integrity artifact a local attacker cannot forge, since it is verified against the trusted IMA keyring \u2014 is silently destroyed and replaced by a locally computed hash written through `__vfs_setxattr_noperm()`, which bypasses the `CAP_SYS_ADMIN` gate in `ima_protect_xattr()`. Combined with the lost write-block, this converts \"signed and immutable\" into \"mutable and re-blessed on close\", a complete integrity bypass of IMA appraisal for the affected file.\nA:H - Once a signature is replaced by a plain hash, any policy carrying IMA_DIGSIG_REQUIRED (`appraise_type=imasig`) rejects that file in enforce mode, so appraised binaries become permanently unexecutable \u2014 applied to system-critical files such as init, sshd, or libc consumers this denies service and can leave the system unbootable, and the corrupted xattr persists on disk until the file is re-signed out of band."

Title
ALSA: firewire-motu: fix buffer overflow in hwdep read for DSP events
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-motu: fix buffer overflow in hwdep read for DSP events
The DSP event handling code in hwdep_read() could write more bytes to
the user buffer than requested, when a user provides a buffer smaller
than the event header size (8 bytes).
Fix by using min_t() to clamp the copy size, This ensures we never copy
more than the user requested.
Severity
7.8 (High)

Title
nbd: defer config unlock in nbd_genl_connect
Summary
In the Linux kernel, the following vulnerability has been resolved:
nbd: defer config unlock in nbd_genl_connect
There is one use-after-free warning when running NBD_CMD_CONNECT and
NBD_CLEAR_SOCK:
nbd_genl_connect
nbd_alloc_and_init_config // config_refs=1
nbd_start_device // config_refs=2
set NBD_RT_HAS_CONFIG_REF open nbd // config_refs=3
recv_work done // config_refs=2
NBD_CLEAR_SOCK // config_refs=1
close nbd // config_refs=0
refcount_inc -> uaf
------------[ cut here ]------------
refcount_t: addition on 0; use-after-free.
WARNING: CPU: 24 PID: 1014 at lib/refcount.c:25 refcount_warn_saturate+0x12e/0x290
nbd_genl_connect+0x16d0/0x1ab0
genl_family_rcv_msg_doit+0x1f3/0x310
genl_rcv_msg+0x44a/0x790
The issue can be easily reproduced by adding a small delay before
refcount_inc(&nbd->config_refs) in nbd_genl_connect():
mutex_unlock(&nbd->config_lock);
if (!ret) {
set_bit(NBD_RT_HAS_CONFIG_REF, &config->runtime_flags);
+ printk("before sleep\n");
+ mdelay(5 * 1000);
+ printk("after sleep\n");
refcount_inc(&nbd->config_refs);
nbd_connect_reply(info, nbd->index);
}

Title
scsi: qla2xxx: Fix improper freeing of purex item
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix improper freeing of purex item
In qla2xxx_process_purls_iocb(), an item is allocated via
qla27xx_copy_multiple_pkt(), which internally calls
qla24xx_alloc_purex_item().
The qla24xx_alloc_purex_item() function may return a pre-allocated item
from a per-adapter pool for small allocations, instead of dynamically
allocating memory with kzalloc().
An error handling path in qla2xxx_process_purls_iocb() incorrectly uses
kfree() to release the item. If the item was from the pre-allocated
pool, calling kfree() on it is a bug that can lead to memory corruption.
Fix this by using the correct deallocation function,
qla24xx_free_purex_item(), which properly handles both dynamically
allocated and pre-allocated items.

Title
libceph: make decode_pool() more resilient against corrupted osdmaps
Summary
In the Linux kernel, the following vulnerability has been resolved:
libceph: make decode_pool() more resilient against corrupted osdmaps
If the osdmap is (maliciously) corrupted such that the encoded length
of ceph_pg_pool envelope is less than what is expected for a particular
encoding version, out-of-bounds reads may ensue because the only bounds
check that is there is based on that length value.
This patch adds explicit bounds checks for each field that is decoded
or skipped.

Title
RDMA/umad: Reject negative data_len in ib_umad_write
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/umad: Reject negative data_len in ib_umad_write
ib_umad_write computes data_len from user-controlled count and the
MAD header sizes. With a mismatched user MAD header size and RMPP
header length, data_len can become negative and reach ib_create_send_mad().
This can make the padding calculation exceed the segment size and trigger
an out-of-bounds memset in alloc_send_rmpp_list().
Add an explicit check to reject negative data_len before creating the
send buffer.

{
"lang": "en",
"value": "AV:L - The vulnerability is in ib_umad_write(), the write handler for /dev/infiniband/umadX character device files, requiring local system access to open and write to the device.\nAC:L - The attacker reliably controls the count parameter passed to write() and can craft input to make data_len negative, triggering the OOB write deterministically with no race or special conditions.\nPR:L - The /dev/infiniband/umadX device has no capability checks in the code path. On RDMA-enabled systems (HPC clusters, cloud servers), udev rules commonly grant access to unprivileged users. An ioctl to register a MAD agent is needed first but requires no special privileges.\nUI:N - No user interaction is required. The attacker directly opens the device file, registers a MAD agent via ioctl, and triggers the bug by writing crafted data.\nS:U - The vulnerability operates within kernel space and does not cross a security boundary such as a VM or sandbox escape.\nC:H - The out-of-bounds memset write into slab memory can corrupt adjacent heap objects. In a controlled exploit, this memory corruption can be leveraged via heap spraying to gain arbitrary read primitives.\nI:H - KASAN confirmed a slab out-of-bounds write of 220 bytes. This heap corruption can be exploited to overwrite adjacent slab objects, enabling arbitrary write primitives and potential code execution.\nA:H - The out-of-bounds write corrupts slab memory, causing kernel crashes as confirmed by the KASAN splat. This is a reliable kernel panic/oops."
