clk: zynqmp: Fix stack-out-of-bounds in strncpy`
"BUG: KASAN: stack-out-of-bounds in strncpy+0x30/0x68"
Linux-ATF interface is using 16 bytes of SMC payload. In case clock name is
longer than 15 bytes, string terminated NULL character will not be received
by Linux. Add explicit NULL character at last byte to fix issues when clock
name is longer.
This fixes below bug reported by KASAN:

tty: serial: sh-sci: fix RSCI FIFO overrun handling
The receive error handling code is shared between RSCI and all other
SCIF port types, but the RSCI overrun_reg is specified as a memory
offset, while for other SCIF types it is an enum value used to index
into the sci_port_params->regs array, as mentioned above the
sci_serial_in() function.
For RSCI, the overrun_reg is CSR (0x48), causing the sci_getreg() call
inside the sci_handle_fifo_overrun() function to index outside the
bounds of the regs array, which currently has a size of 20, as specified
by SCI_NR_REGS.
Because of this, we end up accessing memory outside of RSCI's
rsci_port_params structure, which, when interpreted as a plat_sci_reg,
happens to have a non-zero size, causing the following WARN when
sci_serial_in() is called, as the accidental size does not match the
supported register sizes.
The existence of the overrun_reg needs to be checked because
SCIx_SH3_SCIF_REGTYPE has overrun_reg set to SCLSR, but SCLSR is not
present in the regs array.
Avoid calling sci_getreg() for port types which don't use standard
register handling.
Use the ops->read_reg() and ops->write_reg() functions to properly read
and write registers for RSCI, and change the type of the status variable
to accommodate the 32-bit CSR register.
sci_getreg() and sci_serial_in() are also called with overrun_reg in the
sci_mpxed_interrupt() interrupt handler, but that code path is not used
for RSCI, as it does not have a muxed interrupt.

net: mscc: ocelot: Fix use-after-free caused by cyclic delayed work
The origin code calls cancel_delayed_work() in ocelot_stats_deinit()
to cancel the cyclic delayed work item ocelot->stats_work. However,
cancel_delayed_work() may fail to cancel the work item if it is already
executing. While destroy_workqueue() does wait for all pending work items
in the work queue to complete before destroying the work queue, it cannot
prevent the delayed work item from being rescheduled within the
ocelot_check_stats_work() function. This limitation exists because the
delayed work item is only enqueued into the work queue after its timer
expires. Before the timer expiration, destroy_workqueue() has no visibility
of this pending work item. Once the work queue appears empty,
destroy_workqueue() proceeds with destruction. When the timer eventually
expires, the delayed work item gets queued again, leading to the following
warning:

The following diagram reveals the cause of the above warning:
CPU 0 (remove) | CPU 1 (delayed work callback)
mscc_ocelot_remove() |
ocelot_deinit() | ocelot_check_stats_work()
ocelot_stats_deinit() |
cancel_delayed_work()| ...
| queue_delayed_work()
destroy_workqueue() | (wait a time)
| __queue_work() //UAF
The above scenario actually constitutes a UAF vulnerability.
The ocelot_stats_deinit() is only invoked when initialization
failure or resource destruction, so we must ensure that any
delayed work items cannot be rescheduled.
Replace cancel_delayed_work() with disable_delayed_work_sync()
to guarantee proper cancellation of the delayed work item and
ensure completion of any currently executing work before the
workqueue is deallocated.
A deadlock concern was considered: ocelot_stats_deinit() is called
in a process context and is not holding any locks that the delayed
work item might also need. Therefore, the use of the _sync() variant
is safe here.
This bug was identified through static analysis. To reproduce the
issue and validate the fix, I simulated ocelot-swit

| In the Linux kernel, the following vulnerability has been resolved:
block: fix memory leak in __blkdev_issue_zero_pages
Move the fatal signal check before bio_alloc() to prevent a memory
leak when BLKDEV_ZERO_KILLABLE is set and a fatal signal is pending.
Previously, the bio was allocated before checking for a fatal signal.
If a signal was pending, the code would break out of the loop without
freeing or chaining the just-allocated bio, causing a memory leak.
This matches the pattern already used in __blkdev_issue_write_zeroes()
where the signal check precedes the allocation. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs3: fix uninit memory after failed mi_read in mi_format_new
Fix a KMSAN un-init bug found by syzkaller.
ntfs_get_bh() expects a buffer from sb_getblk(), that buffer may not be
uptodate. We do not bring the buffer uptodate before setting it as
uptodate. If the buffer were to not be uptodate, it could mean adding a
buffer with un-init data to the mi record. Attempting to load that record
will trigger KMSAN.
Avoid this by setting the buffer as uptodate, if it’s not already, by
overwriting it. |
| In the Linux kernel, the following vulnerability has been resolved:
mshv: Fix create memory region overlap check
The current check is incorrect; it only checks if the beginning or end
of a region is within an existing region. This doesn't account for
userspace specifying a region that begins before and ends after an
existing region.
Change the logic to a range intersection check against gfns and uaddrs
for each region.
Remove mshv_partition_region_by_uaddr() as it is no longer used. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: ensure sane device mtu in tunnels
Another syzbot report [1] with no reproducer hints
at a bug in ip6_gre tunnel (dev:ip6gretap0)
Since ipv6 mcast code makes sure to read dev->mtu once
and applies a sanity check on it (see commit b9b312a7a451
"ipv6: mcast: better catch silly mtu values"), a remaining
possibility is that a layer is able to set dev->mtu to
an underflowed value (high order bit set).
This could happen indeed in ip6gre_tnl_link_config_route(),
ip6_tnl_link_config() and ipip6_tunnel_bind_dev()
Make sure to sanitize mtu value in a local variable before
it is written once on dev->mtu, as lockless readers could
catch wrong temporary value.

hd44780_probe() allocates a memory chunk for hd with kzalloc() and

bpf: prevent leak of lsm program after failed attach
In [0], we added the ability to bpf_prog_attach LSM programs to cgroups,
but in our validation to make sure the prog is meant to be attached to
BPF_LSM_CGROUP, we return too early if the check fails. This results in
lack of decrementing prog's refcnt (through bpf_prog_put)
leaving the LSM program alive past the point of the expected lifecycle.
This fix allows for the decrement to take place.

| In the Linux kernel, the following vulnerability has been resolved:
codetag: debug: handle existing CODETAG_EMPTY in mark_objexts_empty for slabobj_ext
When alloc_slab_obj_exts() fails and then later succeeds in allocating a
slab extension vector, it calls handle_failed_objexts_alloc() to mark all
objects in the vector as empty. As a result all objects in this slab
(slabA) will have their extensions set to CODETAG_EMPTY.
Later on if this slabA is used to allocate a slabobj_ext vector for
another slab (slabB), we end up with the slabB->obj_exts pointing to a
slabobj_ext vector that itself has a non-NULL slabobj_ext equal to
CODETAG_EMPTY. When slabB gets freed, free_slab_obj_exts() is called to
free slabB->obj_exts vector.
free_slab_obj_exts() calls mark_objexts_empty(slabB->obj_exts) which will
generate a warning because it expects slabobj_ext vectors to have a NULL
obj_ext, not CODETAG_EMPTY.
Modify mark_objexts_empty() to skip the warning and setting the obj_ext
value if it's already set to CODETAG_EMPTY.
To quickly detect this WARN, I modified the code from
WARN_ON(slab_exts[offs].ref.ct) to BUG_ON(slab_exts[offs].ref.ct == 1);
We then obtained this message:

| In the Linux kernel, the following vulnerability has been resolved:
erofs: avoid infinite loop due to incomplete zstd-compressed data
Currently, the decompression logic incorrectly spins if compressed
data is truncated in crafted (deliberately corrupted) images. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Fix NULL ptr deref by checking new_crtc_state
intel_atomic_get_new_crtc_state can return NULL, unless crtc state wasn't
obtained previously with intel_atomic_get_crtc_state, so we must check it
for NULLness here, just as in many other places, where we can't guarantee
that intel_atomic_get_crtc_state was called.
We are currently getting NULL ptr deref because of that, so this fix was
confirmed to help.
(cherry picked from commit 1d5b09f8daf859247a1ea65b0d732a24d88980d8) |
| In the Linux kernel, the following vulnerability has been resolved:
tty: serial: samsung_tty: Fix a memory leak in s3c24xx_serial_getclk() in case of error
If clk_get_rate() fails, the clk that has just been allocated needs to be
freed. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: ocb: don't leave if not joined
If there's no OCB state, don't ask the driver/mac80211 to
leave, since that's just confusing. Since set/clear the
chandef state, that's a simple check. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: r8712: Fix memory leak in _r8712_init_xmit_priv()
In the above mentioned routine, memory is allocated in several places.
If the first succeeds and a later one fails, the routine will leak memory.
This patch fixes commit 2865d42c78a9 ("staging: r8712u: Add the new driver
to the mainline kernel"). A potential memory leak in
r8712_xmit_resource_alloc() is also addressed. |
