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.

Title
ksmbd: validate zero num_subauth before sub_auth is accessed
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate zero num_subauth before sub_auth is accessed
Access psid->sub_auth[psid->num_subauth - 1] without checking
if num_subauth is non-zero leads to an out-of-bounds read.
This patch adds a validation step to ensure num_subauth != 0
before sub_auth is accessed.

Title
ksmbd: fix overflow in dacloffset bounds check
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix overflow in dacloffset bounds check
The dacloffset field was originally typed as int and used in an
unchecked addition, which could overflow and bypass the existing
bounds check in both smb_check_perm_dacl() and smb_inherit_dacl().
This could result in out-of-bounds memory access and a kernel crash
when dereferencing the DACL pointer.
This patch converts dacloffset to unsigned int and uses
check_add_overflow() to validate access to the DACL.

ksmbd: fix session use-after-free in multichannel connection
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix session use-after-free in multichannel connection
There is a race condition between session setup and
ksmbd_sessions_deregister. The session can be freed before the connection

In multichannel mode, UAF issue can occur in session_deregister
when the second channel sets up a session through the connection of
the first channel. session that is freed through the global session
table can be accessed again through ->sessions of connection.

No local access is needed.\nAC:L - A single deterministically crafted request (DataOffset=0, DataLength=0, CreateContextsLength=20) passes smb2_find_context_vals() and reaches the fixed-offset read every time; there is no race, no timing window, and no dependence on memory layout for the disclosure.\nPR:L - SMB2_CREATE is dispatched only after a valid SessionId (ksmbd_session_lookup) and tree connect, so the attacker needs SMB credentials \u2014 though a guest-mapped share reduces this to effectively none.\nUI:N - The attacker triggers the flaw entirely by sending packets to the listening ksmbd service; no action by any local user or administrator is required.\nS:U - The out-of-bounds read stays within the kernel\u0027s own heap and the impact is confined to the kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 36 bytes of adjacent kernel heap memory are read, and the first 16 (the lease key) are echoed verbatim to the remote attacker in the CREATE response via create_lease_buf(), giving a repeatable heap-disclosure oracle with attacker-controlled allocation sizing for grooming \u2014 sufficient to defeat KASLR and leak neighbouring object contents.\nI:N - The flaw is a read-only over-read; the memcpy destinations are correctly sized kzalloc\u0027d objects and no attacker-controlled out-of-bounds write or control-flow corruption occurs.\nA:H - Because the attacker sizes the kvmalloc\u0027d request buffer, the read can be positioned to run off the end of a vmalloc-backed allocation into a guard page, and on KASAN/hardened kernels it triggers an oops/panic, taking down the SMB server and potentially the system."

Title
acpi: nfit: fix narrowing conversion in acpi_nfit_ctl
Summary
In the Linux kernel, the following vulnerability has been resolved:
acpi: nfit: fix narrowing conversion in acpi_nfit_ctl
Syzkaller has reported a warning in to_nfit_bus_uuid(): "only secondary
bus families can be translated". This warning is emited if the argument
is equal to NVDIMM_BUS_FAMILY_NFIT == 0. Function acpi_nfit_ctl() first
verifies that a user-provided value call_pkg->nd_family of type u64 is
not equal to 0. Then the value is converted to int, and only after that
is compared to NVDIMM_BUS_FAMILY_MAX. This can lead to passing an invalid
argument to acpi_nfit_ctl(), if call_pkg->nd_family is non-zero, while
the lower 32 bits are zero.
Furthermore, it is best to return EINVAL immediately upon seeing the
invalid user input. The WARNING is insufficient to prevent further
undefined behavior based on other invalid user input.
All checks of the input value should be applied to the original variable
call_pkg->nd_family.

There is no network-facing consumer of `acpi_nfit_ctl()`.\nAC:L - Reaching the narrowing bug requires defeating the `bus.c` pre-validation via the double-fetch between the two `copy_from_user()` calls in `__nd_ioctl()`, but the attacker owns both sides of that race \u2014 the user page and the racing thread \u2014 and can make the second fetch deterministic with userfaultfd or a FUSE-backed mapping. NFIT/NVDIMM presence is a standard configuration on persistent-memory servers and QEMU nvdimm guests.\nPR:L - No `capable()` or credential check exists anywhere on the path \u2014 `nd_ioctl()`, `__nd_ioctl()`, `nd_cmd_clear_to_send()` and `acpi_nfit_ctl()` gate solely on the device node\u0027s file permissions and the `O_RDWR` open. Any local account granted access to `/dev/ndctl*` (storage/management group ACLs, or a container handed the device) can drive the full path, so this is an authorized-local-user bug rather than one demanding init-namespace root capabilities.\nUI:N - The attacker triggers everything from their own threads via ioctl and a self-managed racing write; no victim action, mount, or file open is needed.\nS:U - The out-of-bounds read and the WARN both occur within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - A negative narrowed `family` makes `test_bit(family, \u0026nd_desc-\u003ebus_family_mask)` read far outside the one-word bitmap at an attacker-chosen offset spanning roughly 256 MB of kernel memory below the object, and the resulting bit is leaked back through the distinguishable `-EINVAL` vs `-ENOTTY` return. This is an unbounded-window OOB read usable to defeat KASLR and progressively disclose kernel heap contents, not a read strictly bounded to a few bytes.\nI:N - Every consequence of the bad `family` value is a read or an early error return; `guid` is set to NULL but never dereferenced, `array_index_nospec()` clamps the later array index to 0, and no attacker-influenced write to kernel memory occurs.\nA:H - The path hits `WARN_ONCE()` in `to_nfit_bus_uuid()`, which is an immediate kernel panic on the many hardened, Android, and cloud configurations that set `panic_on_warn=1`. Additionally, the wild `bt`-based bitmap access at a large negative offset can land on an unmapped hole and fault, producing an oops."

Title
x86/mm: Fix flush_tlb_range() when used for zapping normal PMDs
Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Fix flush_tlb_range() when used for zapping normal PMDs
On the following path, flush_tlb_range() can be used for zapping normal
PMD entries (PMD entries that point to page tables) together with the PTE
entries in the pointed-to page table:
collapse_pte_mapped_thp
pmdp_collapse_flush
flush_tlb_range
The arm64 version of flush_tlb_range() has a comment describing that it can
be used for page table removal, and does not use any last-level
invalidation optimizations. Fix the X86 version by making it behave the
same way.
Currently, X86 only uses this information for the following two purposes,
which I think means the issue doesn't have much impact:
- In native_flush_tlb_multi() for checking if lazy TLB CPUs need to be
IPI'd to avoid issues with speculative page table walks.
- In Hyper-V TLB paravirtualization, again for lazy TLB stuff.
The patch "x86/mm: only invalidate final translations with INVLPGB" which
is currently under review (see
<https://lore.kernel.org/all/20241230175550.4046587-13-riel@surriel.com/>)
would probably be making the impact of this a lot worse.

Fix the X86 version by making it behave the\nsame way.\n\nCurrently, X86 only uses this information for the following two purposes,\nwhich I think means the issue doesn\u0027t have much impact:\n\n - In native_flush_tlb_multi() for checking if lazy TLB CPUs need to be\n IPI\u0027d to avoid issues with speculative page table walks.\n - In Hyper-V TLB paravirtualization, again for lazy TLB stuff.\n\nThe patch \"x86/mm: only invalidate final translations with INVLPGB\" which\nis currently under review (see\n\u003chttps://lore.kernel.org/all/20241230175550.4046587-13-riel@surriel.com/\u003e)\nwould probably be making the impact of this a lot worse."

"value": "AV:L - The vulnerable path is reached from the `madvise(MADV_COLLAPSE)` syscall (or khugepaged) on the calling process\u0027s own address space, requiring local access to the system. There is no remote or adjacent-network entry point into `pmdp_collapse_flush()`.\nAC:L - The attacker controls every element needed: triggering the PMD zap via `MADV_COLLAPSE` on demand, pinning threads so remote CPUs enter lazy TLB mode with the mm still in CR3, generating kernel work so those lazy CPUs are actively executing, and spraying the page-table page after `pte_free_defer()` releases it. Both sides of the window are attacker-created and the sequence can be repeated indefinitely.\nPR:L - `MADV_COLLAPSE` on the caller\u0027s own mm has no capability check in `mm/madvise.c` (the `CAP_SYS_ADMIN` test at line 1362 covers `MADV_HWPOISON`, and `CAP_SYS_NICE` at line 1803 only applies to remote mms). Any unprivileged local user, including one inside a container or user namespace, can drive the path.\nUI:N - The attacker triggers the collapse entirely from its own process via a syscall; no action by any other user or administrator is needed. khugepaged also reaches the same path autonomously.\nS:U - The stale paging-structure state and any resulting corruption stay within the kernel\u0027s own security authority on the affected host or guest. No IOMMU, hypervisor, or VM boundary is crossed.\nC:H - A lazy-TLB CPU speculatively walking the freed-and-reused page-table page interprets attacker-sprayable memory as PTEs, which can map user virtual addresses to arbitrary physical frames and expose their contents through transient execution. That amounts to an arbitrary physical-memory read primitive rather than a bounded leak.\nI:H - The same bogus paging-structure entries constructed from attacker-controlled data can point a user virtual address at arbitrary physical memory, giving a write primitive over kernel or other-process pages. Corruption of page-table translations is directly leverageable for control-flow hijacking and privilege escalation.\nA:H - Speculative page-table walks over a freed page can resolve to non-existent or non-RAM physical addresses, producing machine checks, oopses, or otherwise unpredictable CPU behavior that panics the machine. Any resulting translation corruption also crashes the affected process and kernel."
