Title
atm: Fix NULL pointer dereference
Summary
In the Linux kernel, the following vulnerability has been resolved:
atm: Fix NULL pointer dereference
When MPOA_cache_impos_rcvd() receives the msg, it can trigger
Null Pointer Dereference Vulnerability if both entry and
holding_time are NULL. Because there is only for the situation
where entry is NULL and holding_time exists, it can be passed
when both entry and holding_time are NULL. If these are NULL,
the entry will be passd to eg_cache_put() as parameter and
it is referenced by entry->use code in it.

"value": "AV:L - The bug is reached through `ioctl(BCH_IOCTL_SUBVOLUME_DESTROY)` on any open file descriptor belonging to a mounted bcachefs filesystem, which requires local access to the system. There is no network-facing path into `bch2_fs_file_ioctl()`.\nAC:L - The attacker deterministically triggers both defects with a single ioctl call \u2014 no race, no memory-layout dependence, no timing window; the dcache state that wedges `bch2_evict_subvolume_inodes()` is created by the attacker simply by walking into the subvolume beforehand. No conditions lie outside the attacker\u0027s control.\nPR:L - `BCH_IOCTL_SUBVOLUME_DESTROY` has no `capable()` check and, before this fix, no `inode_permission()` check, so an ordinary unprivileged local user needs only an fd on the bcachefs mount plus search (`MAY_EXEC`) permission along the path to the victim subvolume. No CAP_SYS_ADMIN, no user-namespace trick, and no ownership of or write access to the target is required.\nUI:N - The attacker issues the ioctl directly with no action by any other user; the mounted bcachefs filesystem is an ambient system configuration, not a victim-performed step at exploit time.\nS:U - The vulnerable code and the impacted resources (kernel filesystem state, on-disk subvolume data) are managed by the same security authority \u2014 the kernel. This is a standard in-kernel DAC-bypass/DoS with no VM, IOMMU, or sandbox boundary crossed.\nC:L - There is no direct arbitrary-read primitive, but the DAC bypass has bounded disclosure consequences: after destroying a root- or other-user-owned subvolume in a directory the attacker can write to, the attacker can recreate the path and have a privileged process deposit sensitive data into attacker-controlled storage, and the non-invalidated dcache subtree leaves stale dentries/inodes referencing a freed subvolume ID that can be reused by another user\u0027s newly created subvolume.\nI:H - An unprivileged user can permanently destroy any subvolume they can merely traverse to \u2014 including root-owned subvolumes and other users\u0027 mode-0700 subvolumes \u2014 bypassing all ownership, write-permission, sticky-bit and non-empty-directory protections, which is unauthorized destruction of arbitrary data on the filesystem. The stale, still-hashed dentry subtree over a deleted subvolume additionally permits writes through inodes whose subvolume ID may be reused.\nA:H - The `d_delete()` bug leaves `bch2_evict_subvolume_inodes()` stuck in `TASK_UNINTERRUPTIBLE`, producing an unkillable D-state kworker that holds `BCH_WRITE_REF_snapshot_delete_pagecache` forever \u2014 unmount and read-only transitions hang, all further subvolume deletions stall, and recovery requires a reboot. Independently, arbitrary destruction of subvolumes (e.g. one holding `/home` or a database) is total loss of the affected data."

Title
netfilter: socket: Lookup orig tuple for IPv6 SNAT
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: socket: Lookup orig tuple for IPv6 SNAT
nf_sk_lookup_slow_v4 does the conntrack lookup for IPv4 packets to
restore the original 5-tuple in case of SNAT, to be able to find the
right socket (if any). Then socket_match() can correctly check whether
the socket was transparent.
However, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks this
conntrack lookup, making xt_socket fail to match on the socket when the
packet was SNATed. Add the same logic to nf_sk_lookup_slow_v6.
IPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, as
pods' addresses are in the fd00::/8 ULA subnet and need to be replaced
with the node's external address. Cilium leverages Envoy to enforce L7
policies, and Envoy uses transparent sockets. Cilium inserts an iptables
prerouting rule that matches on `-m socket --transparent` and redirects
the packets to localhost, but it fails to match SNATed IPv6 packets due
to that missing conntrack lookup.

Title
nfsd: put dl_stid if fail to queue dl_recall
Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: put dl_stid if fail to queue dl_recall
Before calling nfsd4_run_cb to queue dl_recall to the callback_wq, we
increment the reference count of dl_stid.
We expect that after the corresponding work_struct is processed, the
reference count of dl_stid will be decremented through the callback
function nfsd4_cb_recall_release.
However, if the call to nfsd4_run_cb fails, the incremented reference
count of dl_stid will not be decremented correspondingly, leading to the
following nfs4_stid leak:

Title
media: streamzap: fix race between device disconnection and urb callback
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: streamzap: fix race between device disconnection and urb callback
Syzkaller has reported a general protection fault at function
ir_raw_event_store_with_filter(). This crash is caused by a NULL pointer
dereference of dev->raw pointer, even though it is checked for NULL in
the same function, which means there is a race condition. It occurs due
to the incorrect order of actions in the streamzap_disconnect() function:
rc_unregister_device() is called before usb_kill_urb(). The dev->raw
pointer is freed and set to NULL in rc_unregister_device(), and only
after that usb_kill_urb() waits for in-progress requests to finish.
If rc_unregister_device() is called while streamzap_callback() handler is
not finished, this can lead to accessing freed resources. Thus
rc_unregister_device() should be called after usb_kill_urb().
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

It occurs due\nto the incorrect order of actions in the streamzap_disconnect() function:\nrc_unregister_device() is called before usb_kill_urb(). The dev-\u003eraw\npointer is freed and set to NULL in rc_unregister_device(), and only\nafter that usb_kill_urb() waits for in-progress requests to finish.\n\nIf rc_unregister_device() is called while streamzap_callback() handler is\nnot finished, this can lead to accessing freed resources. Thus\nrc_unregister_device() should be called after usb_kill_urb().\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."

Title
media: vimc: skip .s_stream() for stopped entities
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: vimc: skip .s_stream() for stopped entities
Syzbot reported [1] a warning prompted by a check in call_s_stream()
that checks whether .s_stream() operation is warranted for unstarted
or stopped subdevs.
Add a simple fix in vimc_streamer_pipeline_terminate() ensuring that
entities skip a call to .s_stream() unless they have been previously
properly started.
[1] Syzbot report:

Title
arm64: Don't call NULL in do_compat_alignment_fixup()
Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: Don't call NULL in do_compat_alignment_fixup()
do_alignment_t32_to_handler() only fixes up alignment faults for
specific instructions; it returns NULL otherwise (e.g. LDREX). When
that's the case, signal to the caller that it needs to proceed with the
regular alignment fault handling (i.e. SIGBUS). Without this patch, the
kernel panics:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000

Title
tracing: Fix use-after-free in print_graph_function_flags during tracer switching
Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix use-after-free in print_graph_function_flags during tracer switching
Kairui reported a UAF issue in print_graph_function_flags() during
ftrace stress testing [1]. This issue can be reproduced if puting a
'mdelay(10)' after 'mutex_unlock(&trace_types_lock)' in s_start(),
and executing the following script:
$ echo function_graph > current_tracer
$ cat trace > /dev/null &
$ sleep 5 # Ensure the 'cat' reaches the 'mdelay(10)' point
$ echo timerlat > current_tracer
The root cause lies in the two calls to print_graph_function_flags
within print_trace_line during each s_show():
* One through 'iter->trace->print_line()';
* Another through 'event->funcs->trace()', which is hidden in
print_trace_fmt() before print_trace_line returns.
Tracer switching only updates the former, while the latter continues
to use the print_line function of the old tracer, which in the script
above is print_graph_function_flags.
Moreover, when switching from the 'function_graph' tracer to the
'timerlat' tracer, s_start only calls graph_trace_close of the
'function_graph' tracer to free 'iter->private', but does not set
it to NULL. This provides an opportunity for 'event->funcs->trace()'
to use an invalid 'iter->private'.
To fix this issue, set 'iter->private' to NULL immediately after
freeing it in graph_trace_close(), ensuring that an invalid pointer
is not passed to other tracers. Additionally, clean up the unnecessary
'iter->private = NULL' during each 'cat trace' when using wakeup and
irqsoff tracers.

Title
exfat: fix random stack corruption after get_block
Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix random stack corruption after get_block
When get_block is called with a buffer_head allocated on the stack, such
as do_mpage_readpage, stack corruption due to buffer_head UAF may occur in
the following race condition situation.
<CPU 0> <CPU 1>
mpage_read_folio
<<bh on stack>>
do_mpage_readpage
exfat_get_block
bh_read
__bh_read
get_bh(bh)
submit_bh
wait_on_buffer
...
end_buffer_read_sync
__end_buffer_read_notouch
unlock_buffer
<<keep going>>
...
...
...
...
<<bh is not valid out of mpage_read_folio>>
.
.
another_function
<<variable A on stack>>
put_bh(bh)
atomic_dec(bh->b_count)
* stack corruption here *
This patch returns -EAGAIN if a folio does not have buffers when bh_read
needs to be called. By doing this, the caller can fallback to functions
like block_read_full_folio(), create a buffer_head in the folio, and then
call get_block again.
Let's do not call bh_read() with on-stack buffer_head.
