| In the Linux kernel, the following vulnerability has been resolved:
ntfs: fix incorrect MFT record pointer passed to ntfs_attr_record_resize
ntfs_new_attr_flags() passes the wrong MFT record to ntfs_attr_record_resize().
When the attribute is in an extent record, ctx->mrec points to the extent
but the function receives the base record pointer m, causing incorrect
size calculations in memmove.
Fix by passing ctx->mrec (the actual MFT record containing the attribute)
instead of m (the base MFT record) to ntfs_attr_record_resize(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: keep the eviction fence until the last handle is closed
amdgpu_gem_object_close() detaches the user queue eviction fence from
the BO before it checks bo_va->ref_count, so closing any handle of a BO
removes the fence, even when the file still has another handle to the
BO and the bo_va with its GPU mappings stays. The BO can then be evicted
without suspending the user queues of the file, which keep accessing it
through mappings that are only marked for update.
Seen on navi31 with a SDMA user queue: a BO opened twice in the same
file (GEM_FLINK + GEM_OPEN) loses its eviction fence when the second
handle is closed (traced attach/detach of the fence):
attach bo=ffff8c78a6c84c00
GEM_CLOSE handle=7
detach bo=ffff8c78a6c84c00
while handle 6 and the mapping are still in use.
Only detach the fence when the last reference to the bo_va goes away,
matching amdgpu_gem_object_open(), which attaches it only when the
bo_va is created. With this the fence stays until the file is closed.

gpio: shared: fix use-after-free bug when adding shared proxies
The GPIO lookup table can stay alive for longer than the kobject whose
name string's address we're assigning to lookup->dev_id. Fix a potential
UAF by duplicating the string. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/ctcm: Prevent XID null dereference
The mpc_validate_xid() function sets grp->saved_xid2->xid2_flag2 to 0x40
to signal XID validation error. If peer XID is NULL or r/w channel
pairing mismatch happens, grp->saved_xid2 is never initialized. An
attempt to set the flag in such case leads to NULL dereference.
Fix this by using the always available priv->xid->xid2_flag2 instead of
grp->saved_xid2->xid2_flag2 for validation errors. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: validate chunk length in the inqueue parser
SCTP chunks always include a four-byte generic header, but
sctp_inq_pop() currently accepts shorter declared lengths. A zero-length
chunk leaves chunk_end at the current header.
When ASCONF is covered by the association's SCTP-AUTH policy,
sctp_assoc_bh_rcv() can continue before the state machine performs its
normal chunk-length check. sctp_inq_pop() then returns the same malformed
chunk repeatedly and the receive softirq can lock up.
A remote SCTP peer can trigger this after establishing an association on
a kernel built with CONFIG_IP_SCTP and configured with
net.sctp.addip_enable=1 and net.sctp.auth_enable=1. The reproducer did
not require application credentials, a shared SCTP AUTH key, or
net.sctp.addip_noauth_enable=1.
On commit f967455fb2a5 ("seg6: reset IP6CB after IPv6 decapsulation"),
one zero-length ASCONF caused repeated
watchdog soft-lockup reports in a two-vCPU KVM guest. All 3 pre-trigger
health probes succeeded, while 36 of 37 post-trigger probes failed. With
this change, all 37 post-trigger probes succeeded and no equivalent
soft-lockup signature appeared.
Reject chunks shorter than the generic SCTP header at the shared inqueue
parser boundary. Mark the packet for discard before either caller can
continue processing it, while preserving the four-byte generic minimum.
Declared-length 1 through 4 controls and kernel-generated ASCONF traffic
remained healthy. The patched sctp_hello selftest passed for IPv4 and
IPv6.
The complete private reproducer and validation evidence are available
directly to maintainers on request. |
| In the Linux kernel, the following vulnerability has been resolved:
net/iucv: fix the recvmsg window update
iucv_sock_recvmsg() sends the HiperSockets-only AF_IUCV_FLAG_WIN without
testing the transport, so on a classic z/VM socket iucv_send_ctrl() sizes
the skb through a NULL iucv->hs_dev. SO_MSGLIMIT accepts 1, so msglimit / 2
is zero and one recvmsg() on its own socket is enough for an unprivileged
process to take a spurious disconnect.
It also calls iucv_send_ctrl() under spin_lock_bh(&message_q.lock), which
allocates GFP_KERNEL inside a section the code treats as atomic. Sending
outside that lock lets two recvmsg() reach afiucv_hs_send() at once, where
msg_recv is sampled for the advertised window and subtracted after
dev_queue_xmit() -- and sendmsg reaches that counter under lock_sock()
while recvmsg holds no socket lock, so both can subtract the same value,
the counter goes negative and the credit reaches the peer twice.
Test the transport, claim the credit with atomic_xchg() after the last
error exit and hand it back if the transmit fails, and send once the lock
is dropped. |
| In the Linux kernel, the following vulnerability has been resolved:
dm-crypt: fix a tiny race condition in crypt_dec_pending
crypt_dec_pending reads io->error before calling atomic_dec_and_test.
Another context, for example crypt_endio called from an interrupt, may
set io->error and drop its reference between the read and the
decrement. crypt_dec_pending then drops the last reference and completes
the bio with the stale status - so a read that failed and was never
decrypted, or a write that failed, is reported as successful.
The read was placed before the decrement by commit b35f8caa0890 ("dm
crypt: wait for endio to complete before destruction"), because that
commit freed dm_crypt_io before calling bio_endio. This is no longer the
case, dm_crypt_io lives in the per-bio data now.
Read io->error after atomic_dec_and_test instead. atomic_dec_and_test is
fully ordered, so no additional barrier is needed. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Check operator stack capacity before pushing
predicate_parse() uses the first operator stack entry before processing
any opening parentheses. A push then increments top before writing.
The existing check still permits that write when top already points to
the last allocated entry, which can access beyond the operator stack.
Reject the push when top reaches the last allocated entry. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Keep the predicate limit separate from program capacity
predicate_parse() adds two to nr_preds to reserve the terminal TRUE
and FALSE entries. It also uses that increased value as the limit for
parsed predicates. If the initial count is smaller than the number
actually parsed, the program can fill the allocation and subsequent
accesses can go past its end.
Keep nr_preds as the predicate limit and use a separate value for the
allocation size. This leaves space for both terminal entries and a
zeroed entry when parsing stops at the limit. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix NULL sink dereference in USB4 bandwidth functions
allocate_usb4_bandwidth_for_stream() and allocate_usb4_bandwidth() both
use ASSERT(stream->sink) before dereferencing stream->sink->link. ASSERT
is compiled out in production builds, so a NULL stream->sink causes a
NULL pointer dereference.
link_set_dpms_off() already guards two earlier accesses to stream->sink
with explicit NULL checks, confirming that stream->sink can legitimately
be NULL. The subsequent call to deallocate_usb4_bandwidth() had no
equivalent guard.
Replace the ASSERT() calls with proper NULL checks that return false
early, and add a matching stream->sink guard at the call site in
link_set_dpms_off() consistent with the surrounding pattern.
v2: Keep the existing ASSERT() calls for diagnostics (to report
unexpected NULL sink), and add explicit NULL checks that return false
before dereferencing stream->sink. Also add a matching stream->sink
guard at the deallocation call site in link_set_dpms_off(). (Alex)

| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 0.9.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, the repo-server evaluates .jsonnet files with an importer that does not confine import, importstr, or importbin to the repository root. Absolute paths, parent-directory traversal, and repository symlinks can open any file readable by the repo-server, including /proc/self/environ, projected service-account tokens, mounted private keys, and repository credentials. Although generated Secrets are redacted, placing imported contents in a ConfigMap returns the data to the caller. Using importstr on a non-terminating device such as /dev/zero can exhaust repo-server memory. An attacker can commit a .jsonnet file to a Git repository used by an Application or upload the file through POST /api/v1/applications/manifestsWithFiles, also exposed by argocd app diff --local --server-side-generate. Directory applications evaluate every .jsonnet file in the application directory. The upload path requires only Application get permission on an existing directory Application, without Application update or sync permission or repository write access. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2. |

Bluetooth: HIDP: fix missing length checks in hidp_input_report()
hidp_input_report() reads keyboard and mouse payload data from an skb
without first verifying that skb->len contains enough data.
hidp_recv_intr_frame() pulls the 1-byte HIDP header before dispatching
to hidp_input_report(). If a paired device sends a truncated packet,
the handler reads beyond the valid skb data, resulting in an
out-of-bounds read of skb data. The OOB bytes may be interpreted as
phantom key presses or spurious mouse movement.
Replace the open-coded length tracking and pointer arithmetic with
skb_pull_data() calls. skb_pull_data() returns NULL if the requested
bytes are not present, eliminating the need for a manual size variable
and the separate skb->len guard. |

| In the Linux kernel, the following vulnerability has been resolved:
scsi: bsg: Pass reply_len to bsg_setup_queue() to fit UFS ARPMB replies
bsg-lib allocates a 96-byte (SCSI_SENSE_BUFFERSIZE) reply buffer per
job, but struct ufs_rpmb_reply is 104 bytes: a 40-byte struct
ufs_bsg_reply followed by a 64-byte EHS. When an Advanced RPMB command
returns an EHS, ufshcd_advanced_rpmb_req_handler() copies it right after
the 40-byte header and writes 8 bytes past the end of the buffer.
Let each BSG transport pass its reply buffer size to bsg_setup_queue()
and have ufs_bsg request sizeof(struct ufs_rpmb_reply), so the full
reply reaches user space. Other transports keep SCSI_SENSE_BUFFERSIZE. |
| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Fix the sub-buffer array base in rb_meta_subbuf_idx()
On a persistent ring buffer, rb_meta_subbuf_idx() can return an index one
sub-buffer too high. rb_setup_ids_meta_page() then fills subbuf_ids[]
shifted by one and leaves subbuf_ids[0] NULL, which __rb_map_vma()
dereferences when userspace maps trace_pipe_raw. rb_update_meta_reader()
writes two such indices into meta->buffers[], which rb_cpu_meta_valid()
would reject on the next boot, discarding the previous boot's trace.
A CPU's sub-buffer array starts after its meta header and the nr_subbufs
integers that follow, aligned up to a sub-buffer. rb_meta_subbuf_idx()
inverts that calculation but skips only the integers, not the header, so
its base is one sub-buffer low whenever the omitted header size crosses
the alignment boundary.
Invert the calculation with rb_subbufs_from_meta() rather than repeating
it. rb_range_buffer() maps an index back to an address through the same
helper, so the two directions can no longer disagree. |
| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Do not show buffer_meta for CPUs without a buffer
The per_cpu/cpuN/buffer_meta files are created for every possible CPU,
but buffer->buffers[cpu] is only allocated once that CPU comes online.
Reading the file of a CPU that never came online dereferences a NULL
cpu_buffer in rbm_start().
Fail the open with -ENODEV when the CPU has no buffer, as the other
per CPU ring buffer interfaces do. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing/histograms: Reject non-stacktrace fields for synthetic stacktrace fields
In check_synth_field(), when a synthetic event field is a stacktrace
(field->is_stack) and the histogram field is not a "long[" stacktrace
array, validation falls through to the generic size and signedness
comparison.
Because parse_synth_field() sets a stacktrace field's type to
"__data_loc unsigned long[]", its size is sizeof(u64) and
synth_field_signed() marks it as signed. Consequently, any 8-byte
signed scalar histogram field passes the fallback check, and its scalar
value is subsequently dereferenced as a kernel stacktrace pointer in
get_field_size() and trace_stack().
Furthermore, checking strstr(hist_field->type, "long[") is insufficient
because tracepoint fields defined with __bitmask() or __rel_bitmask()
also have type "__data_loc unsigned long[]" or "__rel_loc unsigned
long[]", whilst create_hist_field() treats them as 4-byte scalar values
without HIST_FIELD_FL_STACKTRACE.
Propagate HIST_FIELD_FL_STACKTRACE to variable references and field
variables (whilst excluding variable aliases from per-element
stacktrace capture), and reject any mismatch between
HIST_FIELD_FL_STACKTRACE and field->is_stack in check_synth_field(). |
