| In the Linux kernel, the following vulnerability has been resolved:
nfc: port100: reject frames whose declared length exceeds the received data
port100_recv_response() passes the URB transfer buffer to
port100_rx_frame_is_valid(), which checksums le16_to_cpu(frame->datalen)
bytes of frame->data. datalen is a 16-bit field supplied by the device
and is never checked against the number of bytes actually received
(urb->actual_length), so a device reporting a datalen larger than the
received frame makes port100_data_checksum() read out of bounds past the
transfer buffer.
Reject a response whose declared frame size does not fit the received
length before validating it.
Found by 0sec (https://0sec.ai) using automated source analysis; the
missing bound is evident from source. Compile-tested. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: trf7970a: power down on startup RX gain failure
trf7970a_startup() powers up the device before applying the optional RX
gain reduction. If the register read or write fails, it returns without
undoing that power-up. Probe's unwind only drops the separate regulator
references acquired by probe, leaving the additional VIN enable from
startup unbalanced. The system resume caller also has no power-down on
this error.
Call trf7970a_power_down() before returning the RX gain error to deassert
the enable GPIOs, release the startup VIN reference and restore the
powered-off state. Runtime PM has not been enabled yet, so the full
shutdown helper is not appropriate here. Preserve the original SPI error.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/cio: Fix NULL pointer dereference in ccw_device_get_util_str()
The channel path registry entry associated with a CHPID may be removed
while the subchannel's PMCW still references that CHPID. In this case,
chpid_to_chp() can return NULL, leading to a NULL pointer dereference.
Add the missing NULL check before dereferencing the returned pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: SEV: Do cache maintenance on the source VM during intra-host migration
Manually perform cache maintenance on the source VM during intra-host
migration to ensure no stale data is left in CPU caches after the VM is
destroyed. Because the source VM is "converted" to a non-SEV VM, KVM's
memory reclaim flows won't trigger cache maintenance, e.g. when all guest
memory is reclaimed in response to detaching from the mmu_notifier.
Note, relying on the destination VM to do cache maintenance isn't an option
as KVM doesn't require identical guest memory configurations, i.e. the
source VM may have access to memory that the destination VM does not.
Enforcing equivalent memory configurations is infeasible, as it would
require a *deep* comparison of memslots, e.g. to verify that not only are
the memslot identical, but what the memslots point at is also identical. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Don't WARN on an unknown VM ioctl in protected mode
kvm_pkvm_ioctl_allowed() WARNs when kvm_get_cap_for_kvm_ioctl() doesn't
find the ioctl number in vm_ioctl_caps[], and kvm_arch_vm_ioctl() calls
it for every number the generic code doesn't handle, so
ioctl(vm_fd, 0xdeadbeef) from userspace taints a pKVM host and panics it
under panic_on_warn. The lookup is fed userspace input: return false,
and userspace gets the -EINVAL kvm_arch_vm_ioctl() returns for that
number on a host without pKVM. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix spurious warning for benign stage 2 teardown race
kvmtool was used to establish an L1 guest with 8 CPUs and 8 GiB of RAM, an
L2 guest with 4 CPUs and 4 GiB of RAM and an L3 guest with 2 CPUs and 2 GiB
of RAM, all of which was then exited.
Under memory pressure in the L0 host warnings were observed due to
migration triggered by compaction:
WARNING: arch/arm64/kvm/mmu.c:336 at __unmap_stage2_range+0x64/0x80,
CPU#5: kcompactd0/66
Which was, in turn, triggered by an MMU notifier for the host invalidation:
mmu_notifier_invalidate_range_start()
-> ... -> kvm_mmu_notifier_invalidate_range_start()
-> kvm_mmu_unmap_gfn_range()
-> kvm_unmap_gfn_range()
-> kvm_nested_s2_unmap()
-> kvm_stage2_unmap_range()
-> __unmap_stage2_range()
-> stage2_apply_range()
<- -EINVAL, triggering a WARN_ON()
Racing with L0's teardown of stage 2 page tables:
exit_mm()
-> mmput()
-> __mmput()
-> exit_mmap()
-> mmu_notifier_release()
-> ... -> kvm_mmu_notifier_release()
-> kvm_flush_shadow_all()
-> kvm_arch_flush_shadow_all()
-> kvm_free_stage2_pgd()
-> [ acquire kvm->mmu_lock for write ]
-> mmu->pgt = NULL [ among other tasks ]
-> [ release kvm->mmu_lock for write ]
It turns out there is a benign race resulting in a spurious warning:
Thread A - notify: migration | Thread B - notify: release
-------------------------------|---------------------------------
< kvm->mmu_lock held > |
stage2_apply_range() |
get mmu->pgt, check !NULL |
... | kvm_arch_flush_shadow_all()
cond_resched_rwlock_write(); | < contend, sleep kvm->mmu_lock >

| ...

| ...
| < release kvm->mmu_lock >
[ scheduled ] |

< loop to next > |
get, mmu->pgt, check !NULL |
is NULL, return -EINVAL |
__unmap_stage2_range() |
WARN_ON(-EINVAL) <--- entirely spurious - the race was handled
correctly.
Fix the spurious warning by updating stage2_apply_range() to no longer
treat concurrent PGT teardown on lock release as an error - whether the
walker is tearing down page tables or doing something else this is a
legitimate reason to abort the operation without error.
This keeps the warning in place for all other circumstances.
In practice only __unmap_stage2_range() actually does anything with the
error so this only impacts that. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Derive SCX_RQ_IN_WAKEUP from the core enqueue flags
schedule_deferred_locked() skips scheduling a deferred action while
SCX_RQ_IN_WAKEUP is set and relies on the task_woken_scx() call that follows
a wakeup enqueue to run it. enqueue_task_scx() sets the flag from the merged
enqueue flags, which include the flags stashed for a remote activation.
move_remote_task_to_local_dsq() thus sets SCX_RQ_IN_WAKEUP on the
destination rq when the moved task was woken up, although no
task_woken_scx() follows that activation.
An IMMED insert into a busy destination requests a local reenqueue during
that enqueue. The request gets linked but not scheduled and stays pending
until an unrelated wakeup or preemption on that CPU runs the deferred
actions. The IMMED task sits behind the running task in the meantime. If
nothing runs them before the scheduler is disabled, the request outlives the
scheduler and points into its freed per-cpu area, which the next scheduler
dereferences from run_deferred().
Test the core enqueue flags for the wakeup bit. Only the core's wakeup path
is followed by task_woken_scx(). |

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: validate event length before filtering
is_filtered_packet() reads the event code from skb->data[0] without first
checking that the skb is nonempty. When an opcode filter is configured,
it also reads the command opcode at offsets 3 or 4 without checking that
a Command Complete or Command Status event is long enough.
hci_send_to_sock() invokes the filter before hci_event_packet() validates
the event header. A malformed event supplied by a controller or a vhci
device can therefore cause an out-of-bounds read.
Keep the unmasked event code for the opcode checks. The masked value is
needed for the 64-bit event bitmap, but using it to identify command events
aliases event codes above 0x3f. In particular, Synchronous Train Complete
(0x4f) was treated as Command Status (0x0f) even though its payload has no
opcode.
Reject actual command events that are too short for the field being
inspected. A truncated command event cannot match a configured opcode. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: reject out-of-range OCF values
The raw HCI socket security filter has 128 OCF bits per supported OGF,
but masks the 10-bit OCF with 127 before looking up the command. An
unprivileged socket can therefore submit a reserved OCF that aliases an
allowlisted command modulo 128.
A conforming controller should reject reserved opcodes. Nevertheless,
the security decision must apply to the opcode that will actually be
sent, especially since controller-specific behavior is outside the host
stack's control.
Reject OCF values that cannot be represented by the security filter
instead of aliasing them onto an unrelated command. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: validate frame length before control and FCS access
l2cap_data_rcv() unpacks either a two-byte or four-byte control field
without first ensuring that it is present. A short ERTM or streaming-mode
frame can therefore cause an out-of-bounds read.
There is a second short-frame case when CRC16 is enabled. After the
control field is pulled, l2cap_check_fcs() subtracts two from skb->len
without checking it. If fewer than two bytes remain, the subtraction
wraps; skb_trim() leaves the buffer unchanged and the subsequent FCS
load reads past the logical end of the frame.
Validate that the frame contains both its control field and, when
enabled, its FCS before either field is accessed. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix create context out-of-bounds reads
smb2_parse_contexts() validates the complete create-context area but
does not limit each record to its Next field before dispatching it. A
malformed chain can therefore expose bytes beyond the current context to
a handler. The QFid handler also used a full response-structure cast
although it only reads DiskFileId.
The SMB2/SMB3 lease parsers made the same layout assumption: they read
LeaseState and LeaseFlags at canonical offsets rather than at
DataOffset. A valid non-canonical DataOffset could therefore yield
unrelated in-bounds data, while a short DataLength was still accepted.
Limit each context to its Next value, reject offsets before the context
header, and reject malformed chains. Bound the name range by the current
context and do not dispatch a known handler when DataLength is zero. Read
the QFid DiskFileId only when the context data covers that field. Parse the
lease context from DataOffset and require DataLength to match the v1 or v2
lease_context size used by ksmbd. A size mismatch skips lease parsing
without failing the open. |
