When hfsplus_uni2asc is called from hfsplus_listxattr,
it actually passes in a struct hfsplus_attr_unistr*.
The size of the corresponding structure is different from that of hfsplus_unistr,
so the previous fix (94458781aee6) is insufficient.
The pointer on the unicode buffer is still going beyond the allocated memory.
This patch introduces two warpper functions hfsplus_uni2asc_xattr_str and
hfsplus_uni2asc_str to process two unicode buffers,
struct hfsplus_attr_unistr* and struct hfsplus_unistr* respectively.
When ustrlen value is bigger than the allocated memory size,
the ustrlen value is limited to an safe size.

Local rather than Physical because the volume can be attached locally via a loop device and the trigger is a plain local syscall.\nAC:L - The `length` field of the `hfsplus_attr_unistr` key name is written verbatim by the attacker in the crafted image and was clamped to 255 instead of 127, so the 256-byte overread fires deterministically on the first `listxattr()` call. No race, no heap grooming, and no condition outside the attacker\u0027s control.\nPR:L - Nothing on the `path_listxattrat` \u2192 `vfs_listxattr` \u2192 `hfsplus_listxattr` \u2192 `hfsplus_uni2asc` path performs any capability check \u2014 the only `capable(CAP_SYS_ADMIN)` test (`can_list()`) runs after the out-of-bounds conversion and merely filters `trusted.*` names. Any unprivileged local user who can traverse an HFS+ volume (e.g. one udisks2-automounted from attacker-supplied removable media) triggers it.\nUI:N - In the automount/kiosk scenario the volume is mounted by the system on device insertion with no victim action, and the attacker then issues the `listxattr()` himself; likewise an attacker with loop-mount access performs every step. Choosing the higher-severity option where the mount could otherwise be attributed to a victim.\nS:U - The out-of-bounds read, the leaked bytes, and any resulting fault all stay within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is not a bounded few-byte read: up to 256 bytes past the `kzalloc(536)` key allocation are consumed, NLS-converted into `strbuf`, and copied out to userspace by `copy_name()` plus the `copy_to_user()` in `listxattr()`, giving a direct kernel-heap disclosure channel rather than a mere oracle. On slub_debug/KASAN/KFENCE and hardened configurations those bytes are live redzone/stale slab content adjacent to the allocation.\nI:N - `hfsplus_uni2asc()` only dereferences and converts the input; the output writes are bounded by `*len_p` via `nls-\u003euni2char()` returning `-ENAMETOOLONG`. There is no out-of-bounds write, no type confusion, and no mechanism to modify kernel memory or hijack control flow.\nA:H - The slab out-of-bounds read is a guaranteed KASAN/KFENCE report and, with `panic_on_warn`/`panic_on_oops`, a kernel panic; where the overread crosses a KFENCE guard page it faults outright. It also leaves the xattr listing returning `-EIO`/garbage, rendering the volume\u0027s attribute handling unusable, and is repeatable at will by an unprivileged user."

Title
ublk: fix deadlock when reading partition table
Summary
In the Linux kernel, the following vulnerability has been resolved:
ublk: fix deadlock when reading partition table
When one process(such as udev) opens ublk block device (e.g., to read
the partition table via bdev_open()), a deadlock[1] can occur:
1. bdev_open() grabs disk->open_mutex
2. The process issues read I/O to ublk backend to read partition table
3. In __ublk_complete_rq(), blk_update_request() or blk_mq_end_request()
runs bio->bi_end_io() callbacks
4. If this triggers fput() on file descriptor of ublk block device, the
work may be deferred to current task's task work (see fput() implementation)
5. This eventually calls blkdev_release() from the same context
6. blkdev_release() tries to grab disk->open_mutex again
7. Deadlock: same task waiting for a mutex it already holds
The fix is to run blk_update_request() and blk_mq_end_request() with bottom
halves disabled. This forces blkdev_release() to run in kernel work-queue
context instead of current task work context, and allows ublk server to make
forward progress, and avoids the deadlock.

Title
riscv: Sanitize syscall table indexing under speculation
Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv: Sanitize syscall table indexing under speculation
The syscall number is a user-controlled value used to index into the
syscall table. Use array_index_nospec() to clamp this value after the
bounds check to prevent speculative out-of-bounds access and subsequent
data leakage via cache side channels.
Severity
No CVSS data available.

Title
wifi: wlcore: ensure skb headroom before skb_push
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wlcore: ensure skb headroom before skb_push
This avoids occasional skb_under_panic Oops from wl1271_tx_work. In this case, headroom is
less than needed (typically 110 - 94 = 16 bytes).
Severity
No CVSS data available.

Title
wifi: mac80211: ocb: skip rx_no_sta when interface is not joined
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: ocb: skip rx_no_sta when interface is not joined
ieee80211_ocb_rx_no_sta() assumes a valid channel context, which is only
present after JOIN_OCB.
RX may run before JOIN_OCB is executed, in which case the OCB interface
is not operational. Skip RX peer handling when the interface is not
joined to avoid warnings in the RX path.
Severity
No CVSS data available.

Title
md: suspend array while updating raid_disks via sysfs
Summary
In the Linux kernel, the following vulnerability has been resolved:
md: suspend array while updating raid_disks via sysfs
In raid1_reshape(), freeze_array() is called before modifying the r1bio
memory pool (conf->r1bio_pool) and conf->raid_disks, and
unfreeze_array() is called after the update is completed.
However, freeze_array() only waits until nr_sync_pending and
(nr_pending - nr_queued) of all buckets reaches zero. When an I/O error
occurs, nr_queued is increased and the corresponding r1bio is queued to
either retry_list or bio_end_io_list. As a result, freeze_array() may
unblock before these r1bios are released.
This can lead to a situation where conf->raid_disks and the mempool have
already been updated while queued r1bios, allocated with the old
raid_disks value, are later released. Consequently, free_r1bio() may
access memory out of bounds in put_all_bios() and release r1bios of the
wrong size to the new mempool, potentially causing issues with the
mempool as well.
Since only normal I/O might increase nr_queued while an I/O error occurs,
suspending the array avoids this issue.
Note: Updating raid_disks via ioctl SET_ARRAY_INFO already suspends
the array. Therefore, we suspend the array when updating raid_disks
via sysfs to avoid this issue too.
