Title
rxrpc: fix RESPONSE authenticator parser OOB read
Summary
In the Linux kernel, the following vulnerability has been resolved:
rxrpc: fix RESPONSE authenticator parser OOB read
rxgk_verify_authenticator() copies auth_len bytes into a temporary
buffer and then passes p + auth_len as the parser limit to
rxgk_do_verify_authenticator(). Since p is a __be32 *, that inflates the
parser end pointer by a factor of four and lets malformed RESPONSE
authenticators read past the kmalloc() buffer.
Decoded from the original latest-net reproduction logs with
scripts/decode_stacktrace.sh:

Title
ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()
Sashiko AI-review observed:
In ip6_err_gen_icmpv6_unreach(), the skb is an outer IPv4 ICMP error packet
where its cb contains an IPv4 inet_skb_parm. When skb is cloned into skb2
and passed to icmp6_send(), it uses IP6CB(skb2).
IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm. The cipso
offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm
at offset 18.
If an attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao
would be a non-zero offset. Inside icmp6_send(), mip6_addr_swap() is called
and uses ipv6_find_tlv(skb, opt->dsthao, IPV6_TLV_HAO).
This would scan the inner, attacker-controlled IPv6 packet starting at that
offset, potentially returning a fake TLV without checking if the remaining
packet length can hold the full 18-byte struct ipv6_destopt_hao.
Could mip6_addr_swap() then perform a 16-byte swap that extends past the end
of the packet data into skb_shared_info?
Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and
ip6ip6_err() to prevent this?
This patch implements the first suggestion.
I am not sure if ip6ip6_err() needs to be changed.
A separate patch would be better anyway.

Title
tcp: fix potential race in tcp_v6_syn_recv_sock()
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: fix potential race in tcp_v6_syn_recv_sock()
Code in tcp_v6_syn_recv_sock() after the call to tcp_v4_syn_recv_sock()
is done too late.
After tcp_v4_syn_recv_sock(), the child socket is already visible
from TCP ehash table and other cpus might use it.
Since newinet->pinet6 is still pointing to the listener ipv6_pinfo
bad things can happen as syzbot found.
Move the problematic code in tcp_v6_mapped_child_init()
and call this new helper from tcp_v4_syn_recv_sock() before
the ehash insertion.
This allows the removal of one tcp_sync_mss(), since
tcp_v4_syn_recv_sock() will call it with the correct
context.

A race condition exists in the TCP (Transmission Control Protocol) IPv6 (Internet Protocol version 6) socket handling, specifically within the tcp_v6_syn_recv_sock() function. This occurs because a child socket becomes visible in the TCP hash table before its IPv6-specific information is fully initialized. A remote attacker could potentially exploit this timing window, leading to an unstable system state or unexpected behavior, which may result in a denial of service (DoS)."

Title
scsi: qla2xxx: Completely fix fcport double free
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Completely fix fcport double free
In qla24xx_els_dcmd_iocb() sp->free is set to qla2x00_els_dcmd_sp_free().
When an error happens, this function is called by qla2x00_sp_release(),
when kref_put() releases the first and the last reference.
qla2x00_els_dcmd_sp_free() frees fcport by calling qla2x00_free_fcport().
Doing it one more time after kref_put() is a bad idea.

Title
RDMA/iwcm: Fix workqueue list corruption by removing work_list
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/iwcm: Fix workqueue list corruption by removing work_list
The commit e1168f0 ("RDMA/iwcm: Simplify cm_event_handler()")
changed the work submission logic to unconditionally call
queue_work() with the expectation that queue_work() would
have no effect if work was already pending. The problem is
that a free list of struct iwcm_work is used (for which
struct work_struct is embedded), so each call to queue_work()
is basically unique and therefore does indeed queue the work.
This causes a problem in the work handler which walks the work_list
until it's empty to process entries. This means that a single
run of the work handler could process item N+1 and release it
back to the free list while the actual workqueue entry is still
queued. It could then get reused (INIT_WORK...) and lead to
list corruption in the workqueue logic.
Fix this by just removing the work_list. The workqueue already
does this for us.
This fixes the following error that was observed when stress
testing with ucmatose on an Intel E830 in iWARP mode:
[ 151.465780] list_del corruption. next->prev should be ffff9f0915c69c08, but was ffff9f0a1116be08. (next=ffff9f0a15b11c08)

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/iwcm: Fix workqueue list corruption by removing work_list\n\nThe commit e1168f0 (\"RDMA/iwcm: Simplify cm_event_handler()\")\nchanged the work submission logic to unconditionally call\nqueue_work() with the expectation that queue_work() would\nhave no effect if work was already pending. The problem is\nthat a free list of struct iwcm_work is used (for which\nstruct work_struct is embedded), so each call to queue_work()\nis basically unique and therefore does indeed queue the work.\n\nThis causes a problem in the work handler which walks the work_list\nuntil it\u0027s empty to process entries. This means that a single\nrun of the work handler could process item N+1 and release it\nback to the free list while the actual workqueue entry is still\nqueued. It could then get reused (INIT_WORK...) and lead to\nlist corruption in the workqueue logic.\n\nFix this by just removing the work_list. The workqueue already\ndoes this for us.\n\nThis fixes the following error that was observed when stress\ntesting with ucmatose on an Intel E830 in iWARP mode:\n\n[ 151.465780] list_del corruption. next-\u003eprev should be ffff9f0915c69c08, but was ffff9f0a1116be08.

Title
selinux: fix overlayfs mmap() and mprotect() access checks
Summary
In the Linux kernel, the following vulnerability has been resolved:
selinux: fix overlayfs mmap() and mprotect() access checks
The existing SELinux security model for overlayfs is to allow access if
the current task is able to access the top level file (the "user" file)
and the mounter's credentials are sufficient to access the lower
level file (the "backing" file). Unfortunately, the current code does
not properly enforce these access controls for both mmap() and mprotect()
operations on overlayfs filesystems.
This patch makes use of the newly created security_mmap_backing_file()
LSM hook to provide the missing backing file enforcement for mmap()
operations, and leverages the backing file API and new LSM blob to
provide the necessary information to properly enforce the mprotect()
access controls.

Title
RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()
Sashiko points out that the user can specify WQs sharing the same CQ as a
part of the uAPI and this will trigger the WARN_ON() then go on to corrupt
the kernel.
Just reject it outright and fail the QP creation.
Severity
CWE
- CWE-1288 - Improper Validation of Consistency within Input

Title
nvmet-tcp: fix race between ICReq handling and queue teardown
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: fix race between ICReq handling and queue teardown
nvmet_tcp_handle_icreq() updates queue->state after sending an
Initialization Connection Response (ICResp), but it does so without
serializing against target-side queue teardown.
If an NVMe/TCP host sends an Initialization Connection Request
(ICReq) and immediately closes the connection, target-side teardown
may start in softirq context before io_work drains the already
buffered ICReq. In that case, nvmet_tcp_schedule_release_queue()
sets queue->state to NVMET_TCP_Q_DISCONNECTING and drops the queue
reference under state_lock.
If io_work later processes that ICReq, nvmet_tcp_handle_icreq() can
still overwrite the state back to NVMET_TCP_Q_LIVE. That defeats the
DISCONNECTING-state guard in nvmet_tcp_schedule_release_queue() and
allows a later socket state change to re-enter teardown and issue a
second kref_put() on an already released queue.
The ICResp send failure path has the same problem. If teardown has
already moved the queue to DISCONNECTING, a send error can still
overwrite the state with NVMET_TCP_Q_FAILED, again reopening the
window for a second teardown path to drop the queue reference.
Fix this by serializing both post-send state transitions with
state_lock and bailing out if teardown has already started.
Use -ESHUTDOWN as an internal sentinel for that bail-out path rather
than propagating it as a transport error like -ECONNRESET. Keep
nvmet_tcp_socket_error() setting rcv_state to NVMET_TCP_RECV_ERR before
honoring that sentinel so receive-side parsing stays quiesced until the
existing release path completes.

In that case, nvmet_tcp_schedule_release_queue()\nsets queue-\u003estate to NVMET_TCP_Q_DISCONNECTING and drops the queue\nreference under state_lock.\n\nIf io_work later processes that ICReq, nvmet_tcp_handle_icreq() can\nstill overwrite the state back to NVMET_TCP_Q_LIVE. That defeats the\nDISCONNECTING-state guard in nvmet_tcp_schedule_release_queue() and\nallows a later socket state change to re-enter teardown and issue a\nsecond kref_put() on an already released queue.\n\nThe ICResp send failure path has the same problem. If teardown has\nalready moved the queue to DISCONNECTING, a send error can still\noverwrite the state with NVMET_TCP_Q_FAILED, again reopening the\nwindow for a second teardown path to drop the queue reference.\n\nFix this by serializing both post-send state transitions with\nstate_lock and bailing out if teardown has already started.\n\nUse -ESHUTDOWN as an internal sentinel for that bail-out path rather\nthan propagating it as a transport error like -ECONNRESET. Keep\nnvmet_tcp_socket_error() setting rcv_state to NVMET_TCP_RECV_ERR before\nhonoring that sentinel so receive-side parsing stays quiesced until the\nexisting release path completes."

Title
RDMA/mana: Validate rx_hash_key_len
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mana: Validate rx_hash_key_len
Sashiko points out that rx_hash_key_len comes from a uAPI structure and is
blindly passed to memcpy, allowing the userspace to trash kernel
memory. Bounds check it so the memcpy cannot overflow.
Severity
CWE
- CWE-787 - Out-of-bounds Write

Title
KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry
vgic_its_invalidate_cache() walks the per-ITS translation cache with
xa_for_each() and drops the cache's reference on each entry with
vgic_put_irq(). It puts the iterated pointer, though, rather than the
value returned by xa_erase().
The function is called from contexts that do not exclude one another: the
ITS command handlers hold its_lock, the GITS_CTLR write path holds
cmd_lock, and the path that clears EnableLPIs in a redistributor's
GICR_CTLR holds neither. Two or more of them can drain the same cache
concurrently, and if each one observes the same entry, erases it and then
puts it, the single reference the cache holds on that entry is dropped
more than once. The entry can then be freed while an ITE still maps it.
xa_erase() is atomic and returns the previous entry, so put only the entry
that this context actually removed. The cache reference is then dropped
exactly once per entry even when the invalidations run concurrently, and
the behavior is unchanged when only one context runs.

This vulnerability occurs when multiple concurrent operations incorrectly drop the translation cache\u0027s reference to an entry more than once during cache invalidation. This leads to a use-after-free condition, which can result in memory corruption. The primary impact is potential system instability or a denial of service."
