The issue occurs in the following scenarios:
nsim_dev_trap_fa_cookie_write()
kmalloc() fa_cookie
nsim_dev->fa_cookie = fa_cookie
..
nsim_drv_remove()
The fa_cookie allocked in nsim_dev_trap_fa_cookie_write() is not freed. To
fix, add kfree(nsim_dev->fa_cookie) to nsim_drv_remove().

Title
bus: mhi: host: Add alignment check for event ring read pointer
Summary
In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Add alignment check for event ring read pointer
Though we do check the event ring read pointer by "is_valid_ring_ptr"
to make sure it is in the buffer range, but there is another risk the
pointer may be not aligned. Since we are expecting event ring elements
are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer
could lead to multiple issues like DoS or ring buffer memory corruption.
So add a alignment check for event ring read pointer.

Title
Bluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()
Extend a critical section to prevent chan from early freeing.
Also make the l2cap_connect() return type void. Nothing is using the
returned value but it is ugly to return a potentially freed pointer.
Making it void will help with backports because earlier kernels did use
the return value. Now the compile will break for kernels where this
patch is not a complete fix.

No precondition lies outside the attacker\u0027s control.\nPR:N - l2cap_bredr_sig_cmd() processes L2CAP_CONN_REQ on the fixed signalling CID 0x0001 with no authentication, and l2cap_connect() explicitly bypasses hci_conn_check_link_mode() for the always-listening SDP PSM 0x0001. An unpaired, unauthenticated remote device needs no credentials on the target.\nUI:N - Exploitation only requires the target to be connectable, which is the default state for phones, headsets, car head units, laptops and embedded devices with Bluetooth enabled. No victim action of any kind is needed.\nS:U - The corruption is of kernel slab memory handled by the kernel itself; the vulnerable component and the impacted component share the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed chan is read and its fields (imtu, max_tx, tx_win, fcs, retrans/monitor timeouts) are packed into an L2CAP Configuration Request sent back over the air, leaking reallocated slab contents directly to the attacker, and chan-\u003econn is dereferenced as a pointer taken from freed memory, giving an arbitrary-read primitive once the slab is groomed.\nI:H - After the free the code performs set_bit(CONF_REQ_SENT, \u0026chan-\u003econf_state) and chan-\u003enum_conf_req++, writing into the freed slab, and the object holds the ops function-pointer table and data/conn pointers, so heap spraying yields a write primitive and control-flow hijack potential.\nA:H - This is a slab use-after-free that reliably produces KASAN splats, memory corruption, and kernel oops/panic, and it can be re-triggered repeatedly by an unauthenticated in-range attacker to keep the system down."

Title
dlm: prevent NPD when writing a positive value to event_done
Summary
In the Linux kernel, the following vulnerability has been resolved:
dlm: prevent NPD when writing a positive value to event_done
do_uevent returns the value written to event_done. In case it is a
positive value, new_lockspace would undo all the work, and lockspace
would not be set. __dlm_new_lockspace, however, would treat that
positive value as a success due to commit 8511a2728ab8 ("dlm: fix use
count with multiple joins").
Down the line, device_create_lockspace would pass that NULL lockspace to
dlm_find_lockspace_local, leading to a NULL pointer dereference.
Treating such positive values as successes prevents the problem. Given
this has been broken for so long, this is unlikely to break userspace
expectations.
Severity
No CVSS data available.

Title
crypto: af_alg - Set merge to zero early in af_alg_sendmsg
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Set merge to zero early in af_alg_sendmsg
If an error causes af_alg_sendmsg to abort, ctx->merge may contain
a garbage value from the previous loop. This may then trigger a
crash on the next entry into af_alg_sendmsg when it attempts to do
a merge that can't be done.
Fix this by setting ctx->merge to zero near the start of the loop.

7.8 (High)

Title
fs: quota: create dedicated workqueue for quota_release_work
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: quota: create dedicated workqueue for quota_release_work
There is a kernel panic due to WARN_ONCE when panic_on_warn is set.
This issue occurs when writeback is triggered due to sync call for an
opened file(ie, writeback reason is WB_REASON_SYNC). When f2fs balance
is needed at sync path, flush for quota_release_work is triggered.
By default quota_release_work is queued to "events_unbound" queue which
does not have WQ_MEM_RECLAIM flag. During f2fs balance "writeback"
workqueue tries to flush quota_release_work causing kernel panic due to
MEM_RECLAIM flag mismatch errors.
This patch creates dedicated workqueue with WQ_MEM_RECLAIM flag
for work quota_release_work.

In the Linux kernel, the following vulnerability has been resolved:
net/sched: cls_u32: use skb_header_pointer_careful()
skb_header_pointer() does not fully validate negative @offset values.
Use skb_header_pointer_careful() instead.
GangMin Kim provided a report and a repro fooling u32_classify():

The attacker configures the filter and sends packets themselves within their network namespace.\nS:U - The vulnerability operates within the kernel\u0027s security domain. There is no crossing of security boundaries such as VM escape or sandbox escape.\nC:H - The out-of-bounds read allows reading arbitrary adjacent slab memory with attacker-controlled offsets. The classification result can serve as a side-channel oracle to leak kernel memory contents byte-by-byte.\nI:N - This is strictly an out-of-bounds read vulnerability. The read data is used only for comparison in the classifier; no write primitive exists in this code path.\nA:H - Accessing out-of-bounds slab memory with a sufficiently large negative offset can hit unmapped pages, causing a kernel oops/crash as confirmed by the KASAN slab-out-of-bounds report."

Title
ext4: replace BUG_ON with proper error handling in ext4_read_inline_folio
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: replace BUG_ON with proper error handling in ext4_read_inline_folio
Replace BUG_ON() with proper error handling when inline data size
exceeds PAGE_SIZE. This prevents kernel panic and allows the system to
continue running while properly reporting the filesystem corruption.
The error is logged via ext4_error_inode(), the buffer head is released
to prevent memory leak, and -EFSCORRUPTED is returned to indicate
filesystem corruption.
Severity
No CVSS data available.

Title
ksmbd: fix mechToken leak when SPNEGO decode fails after token alloc
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix mechToken leak when SPNEGO decode fails after token alloc
The kernel ASN.1 BER decoder calls action callbacks incrementally as it
walks the input. When ksmbd_decode_negTokenInit() reaches the mechToken
[2] OCTET STRING element, ksmbd_neg_token_alloc() allocates
conn->mechToken immediately via kmemdup_nul(). If a later element in
the same blob is malformed, then the decoder will return nonzero after
the allocation is already live. This could happen if mechListMIC [3]
overrunse the enclosing SEQUENCE.
decode_negotiation_token() then sets conn->use_spnego = false because
both the negTokenInit and negTokenTarg grammars failed. The cleanup at
the bottom of smb2_sess_setup() is gated on use_spnego:
if (conn->use_spnego && conn->mechToken) {
kfree(conn->mechToken);
conn->mechToken = NULL;
}
so the kfree is skipped, causing the mechToken to never be freed.
This codepath is reachable pre-authentication, so untrusted clients can
cause slow memory leaks on a server without even being properly
authenticated.
Fix this up by not checking check for use_spnego, as it's not required,
so the memory will always be properly freed. At the same time, always
free the memory in ksmbd_conn_free() incase some other failure path
forgot to free it.
Severity
No CVSS data available.
