| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: reject oversized IBs with per-ring packet limits
On GFX rings, amdgpu_cs_p2_ib() passed user-supplied ib_bytes through
to ib->length_dw without a limit, while ring_emit_ib() encodes length
into packet fields. Oversized values can corrupt adjacent control bits
and destabilize command submission.
Add a per-ring IB packet size limit helper and reject command
submissions exceeding the corresponding dword limit before IB
allocation. Use the documented 20-bit limit for GFX/compute/SDMA/VPE,
and apply the MM fallback limit for other ring types.
(cherry picked from commit 7f48fa2cf62e3fa6c9c3870aa74988f773247e52) |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: core: Fix pointer desynchronization in fb_io_read()
In fb_io_read(), if copy_to_user() performs a partial copy (e.g., due to
a faulty user buffer), the loop adjusts the chunk size 'c' and updates
the remaining 'count'. However, the hardware 'src' pointer has already
been eagerly advanced by the original chunk size.
If the loop is allowed to continue, the read will resume from an
incorrect, over-advanced offset. Since the remaining 'count' was only
decremented by the successful bytes, this desynchronization causes the
next iterations to execute more hardware reads than originally bounded,
eventually leading to out-of-bounds I/O reads.
Fix this by breaking out of the loop immediately upon a partial
copy_to_user(). A partial copy indicates a faulty user buffer, making
subsequent read attempts futile. Breaking out ensures we return the
number of successfully read bytes without risking out-of-bounds hardware
accesses in subsequent mismatched iterations. |
| In the Linux kernel, the following vulnerability has been resolved:
mptcp: reclaim forward-allocated memory on RX path errors
After commit 9db5b3cec4ec ("mptcp: borrow forward memory from subflow"),
errors in the receive path prior to queueing skbs into the receive
queue do not trigger forward-allocated memory reclaiming.
Prevent forward memory from growing unboundedly in pathological drop
scenarios by explicitly reclaiming memory when skbs are dropped. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: cls_bpf: reject dev-bound programs bound to a different device
cls_bpf_prog_from_efd() obtained a SCHED_CLS program via
bpf_prog_get_type_dev() but never verified that a device-bound (offloaded)
program's bound netdev matches the TC netdev the classifier is being
attached to. This let a program loaded with prog_ifindex for device A be
attached via cls_bpf + skip_sw to device B; deleting device A then
destroyed the program's offload state while it was still attached to
device B, triggering a netdevsim WARN (panic with panic_on_warn=1).
Mirror the XDP attach path (net/core/dev.c) and reject the attach with
-EINVAL when a dev-bound program's bound device does not match the
target device. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: ti: am65-cpsw-nuss: Fix port_id extraction from SRC TAG
On the packet reception path, the ID of the MAC Port on which the packet
was received, is embedded in the RX DMA Descriptor's metadata. The ID is
extracted using the helper function cppi5_desc_get_tags_ids() which fills
in the 16-bit Source Tag into the 'port_id' variable. However, it is only
the lower 8-bits of the 16-bit Source Tag that represent the MAC Port ID,
while the upper 8-bits are Hardware-Reserved and carry an arbitrary value.
With the existing logic, sporadic kernel crash is observed due to the
subsequent driver code accessing out-of-bound memory because of an invalid
port_id.
Hence, fix the port_id extraction logic to use only the lower 8-bits of the
Source Tag as the MAC Port ID. |
| In the Linux kernel, the following vulnerability has been resolved:
macvlan: inherit needed_headroom and needed_tailroom from lowerdev
macvlan devices inherit hard_header_len from lowerdev during macvlan_init(),
but leave needed_headroom and needed_tailroom set to 0.
When the underlying lowerdev requires extra headroom or tailroom for
headers/trailers (e.g. macsec, ipsec, wireguard, tunnels, or veth with rx
headroom), upper layers calculating packet headroom and tailroom fail to
reserve sufficient space.
This can result in reallocation overhead, skb headroom underflows, or KASAN
slab-use-after-free crashes when dev_hard_header() / macvlan_hard_header()
prepends header data or when lower devices append tailroom.
Fix this by:
1. Inheriting needed_headroom and needed_tailroom from lowerdev in macvlan_init().
2. Propagating needed_headroom and needed_tailroom updates to attached macvlans
in macvlan_device_event() when receiving NETDEV_FEAT_CHANGE events. |

s390/zcrypt: Improve CCA CPRB length and overflow checks
The xcrb_msg_to_type6cprb_msgx() function lacks proper input
validation, creating security vulnerabilities:
1. Integer overflow after CEIL4 alignment: Signed int variables could
overflow during 4-byte boundary alignment, causing undersized
buffer allocations or incorrect bounds checking.
2. Missing minimum size validation: The CPRBX structure is copied from
userspace without verifying sufficient buffer length. Undersized
buffers cause uninitialized memory access when reading structure
fields like cprbx.cprb_len and cprbx.domain.
3. Arithmetic overflow in sum calculations: Adding control block and
data block sizes could overflow, bypassing size checks and enabling
buffer overflows.
Fix by using size_t for length calculations, adding U32_MAX boundary
checks after alignment, validating minimum control block size before
copying from userspace, and detecting sum calculation overflows. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: cs40l50-vibra - validate custom data from user space
cs40l50_add() copies the custom data of an FF_PERIODIC/FF_CUSTOM effect
straight from the ff_effect the user passed to EVIOCSFF, without
requiring it to hold anything:
work_data.custom_data = memdup_array_user(periodic->custom_data,
periodic->custom_len,
sizeof(s16));
work_data.custom_len = periodic->custom_len;
The driver then reads two words out of that buffer: custom_data[0] as the
waveform bank in cs40l50_effect_bank_set(), and custom_data[1] as the
index within the bank in cs40l50_effect_index_set(). Neither read is
covered by a length check, and custom_len is fully user controlled:
- custom_len == 0 makes memdup_array_user() call memdup_user() with a
length of zero, which returns ZERO_SIZE_PTR rather than an error, so
custom_data[0] dereferences it.
- custom_len == 1 allocates two bytes. A bank of ROM or RAM keeps
effect->type out of the OWT case, and custom_data[1] is then read one
word past the allocation.
The bank value itself is also mishandled. It is masked with
CS40L50_CUSTOM_DATA_MASK (0xffff) but stored in an s16, so a
custom_data[0] of 0x8000 or above wraps to a negative value that passes
the "bank_type >= CS40L50_WVFRM_BANK_NUM" test.
cs40l50_effect_index_set() indexes vib->dsp.banks[] with it before the
switch statement's default case gets a chance to reject it:
base_index = vib->dsp.banks[effect->type].base_index;
max_index = vib->dsp.banks[effect->type].max_index;
Require the two words the driver reads to be present, and hold the masked
bank in a u32 so the existing upper-bound test covers the whole range.
The da7280 haptic driver already range checks custom_len this way. |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: clear fb_info->mode before deleting a videomode
fb_set_var() can delete a mode from info->modelist when userspace
passes FB_ACTIVATE_INV_MODE through FBIOPUT_VSCREENINFO. The code
checks that the mode being deleted is not the current info->var and
that fbcon is not using it, but it does not check fb_info->mode.
fb_info->mode may still point into the modelist entry being deleted.
If the entry is freed, later mode sysfs reads through show_mode() can
dereference a stale pointer.
Clear fb_info->mode before calling fb_delete_videomode() when it
matches the mode being removed. |
| In the Linux kernel, the following vulnerability has been resolved:
mptcp: fastopen: only mark MPTFO subflows with SYN data
Passive TCP Fast Open accepts a valid-cookie SYN even when it carries
no data. In that case the child socket's receive queue is intentionally
left empty.
mptcp_fastopen_subflow_synack_set_params() set is_mptfo before checking
for queued SYN data. That made data-less TFO SYNs hit a WARN and, if
the warning was non-fatal, left stale MPTFO state behind. The stale
flag could later trigger a state-confusion bug in
check_fully_established().
Only mark the subflow as MPTFO after confirming that an SKB was queued.
Return quietly when the receive queue is empty.
Note that mptcp_subflow_context's is_mptfo field is now not just about
subflows where the TFO was present, but about MPTFO subflow that
consumed SYN data. Only having a valid cookie but not carrying data is
not really "doing TFO". |

Input: focaltech - fix array out-of-bounds in focaltech_process_rel_packet
Make finger2 (and also finger1) unsigned, so that if the finger index in
the packet is 0 then subtracting 1 creates an array index which overflows
above the existing check for FOC_MAX_FINGERS, as the existing comment says
it should, instead of writing to state->fingers[-1]. |

| A flaw was found in glibc. This vulnerability allows a remote attacker to cause a denial of service (DoS) by providing specially crafted text to an application that converts text from SHIFT_JISX0213 to UCS-4. The crafted input can lead to a continuous loop of processing, preventing the application from making progress and consuming resources. Exploitation requires specific conditions, including the application retrying conversion after an error with limited output space. |

| In the Linux kernel, the following vulnerability has been resolved:
libceph: fix multiple unsafe decodes in decode_locker()
decode_locker() in cls_lock_client.c contains three unsafe decode
operations that allow a malicious or compromised OSD to trigger
slab-out-of-bounds reads:
1. ceph_decode_copy() at the locker_id_t name field has no preceding
bounds check. With p == end after ceph_start_decoding() accepts
struct_len=0, this reads sizeof(ceph_entity_name) = 9 bytes past
the validated buffer boundary.
2. *p += sizeof(struct ceph_timespec) after the locker_info_t header
is an unchecked pointer advance. A malicious OSD can position p
past end, causing all subsequent _safe checks to pass against a
bogus boundary.
3. len = ceph_decode_32(p) has no preceding bounds check, and the
immediately following *p += len is uncapped. A malicious OSD can
send len=0xffffffff, advancing p gigabytes past end and escaping
the decode window entirely.
Fix all three by replacing bare operations with their safe variants:
ceph_decode_copy -> ceph_decode_copy_safe
*p += sizeof(...) -> ceph_decode_skip_n
ceph_decode_32(p) -> ceph_decode_32_safe
*p += len -> ceph_decode_skip_n
A new label is added to return -EINVAL on any bounds violation.
-EINVAL is appropriate here: the data received from the OSD
is structurally malformed, which is an invalid argument to the decode
contract regardless of whether the caller or the wire is at fault.
Attacker model: a malicious or compromised OSD in a multi-tenant Ceph
deployment can trigger this against any kernel client that issues the
lock.get_info class method (e.g. during RBD exclusive lock acquisition)
without any further privileges beyond OSD session establishment.
