drm/i915: Fix potential overflow of shmem scatterlist length
When a scatterlists table of a GEM shmem object of size 4 GB or more is
populated with pages allocated from a folio, unsigned int .length
attribute of a scatterlist may get overflowed if total byte length of
pages allocated to that single scatterlist happens to reach or cross the
4GB limit. As a consequence, users of the object may suffer from hitting
unexpected, premature end of the object's backing pages.

That issue was apprehended by the author of a change that introduced it,
and potential risk even annotated with a comment, but then never addressed.
When adding folio pages to a scatterlist table, take care of byte length
of any single scatterlist not exceeding max_segment.

| libyang is a YANG data modeling language library. Prior to SO 5.2.15, lyb_read_string() in src/parser_lyb.c contains an integer overflow that results in a heap buffer overflow when parsing a maliciously crafted LYB binary blob. An attacker who can supply LYB data to any libyang consumer (NETCONF server, sysrepo, etc.) can trigger a crash or potential heap corruption. This vulnerability is fixed in SO 5.2.15. |
| In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Fix PM runtime usage count underflow
Replace pm_runtime_put_sync() with pm_runtime_dont_use_autosuspend() in
the remove path to properly pair with pm_runtime_use_autosuspend() from
probe. This allows pm_runtime_disable() to handle reference count cleanup
correctly regardless of current suspend state.
The driver calls pm_runtime_put_sync() unconditionally in remove, but the
device may already be suspended due to autosuspend configured in probe.
When autosuspend has already suspended the device, the usage count is 0,
and pm_runtime_put_sync() decrements it to -1.
This causes the following warning on module unload:

| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix transaction abort on set received ioctl due to item overflow
If the set received ioctl fails due to an item overflow when attempting to
add the BTRFS_UUID_KEY_RECEIVED_SUBVOL we have to abort the transaction
since we did some metadata updates before.
This means that if a user calls this ioctl with the same received UUID
field for a lot of subvolumes, we will hit the overflow, trigger the
transaction abort and turn the filesystem into RO mode. A malicious user
could exploit this, and this ioctl does not even requires that a user
has admin privileges (CAP_SYS_ADMIN), only that he/she owns the subvolume.
Fix this by doing an early check for item overflow before starting a
transaction. This is also race safe because we are holding the subvol_sem
semaphore in exclusive (write) mode.
A test case for fstests will follow soon. |
| vLLM is an inference and serving engine for large language models (LLMs). From to before 0.20.0, the extract_hidden_states speculative decoding proposer in vLLM returns a tensor with an incorrect shape after the first decode step, causing a RuntimeError that crashes the EngineCore process. The crash is triggered when any request in the batch uses sampling penalty parameters (repetition_penalty, frequency_penalty, or presence_penalty). A single request with a penalty parameter (e.g., "repetition_penalty": 1.1) is sufficient to crash the server. This vulnerability is fixed in 0.20.0. |
| Improper input validation in the AMD OverDrive (AOD) System Management Mode (SMM) module could allow a privileged attacker to perform an out-of-bounds read, potentially resulting in loss of confidentiality. |
| Improper Input validation in the AMD Secure Processor (ASP) PCI driver may allow a local attacker to create a buffer overflow condition, potentially resulting in a crash or denial of service |
| Improper isolation of GPU HW register space could allow a privileged attacker in malicious Guest Virtual Machine (VM) to perform unauthorized access to specific victim range of GPU MMIO register space, potentially causing the host OS to reboot and creating a Denial of Service (DOS) condition. |

drm/v3d: Set DMA segment size to avoid debug warnings
When using V3D rendering with CONFIG_DMA_API_DEBUG enabled, the
kernel occasionally reports a segment size mismatch. This is because
'max_seg_size' is not set. The kernel defaults to 64K. setting
'max_seg_size' to the maximum will prevent 'debug_dma_map_sg()'
from complaining about the over-mapping of the V3D segment length.
DMA-API: v3d 1002000000.v3d: mapping sg segment longer than device
claims to support [len=8290304] [max=65536]

| In the Linux kernel, the following vulnerability has been resolved:
libceph: define and enforce CEPH_MAX_KEY_LEN
When decoding the key, verify that the key material would fit into
a fixed-size buffer in process_auth_done() and generally has a sane
length.
The new CEPH_MAX_KEY_LEN check replaces the existing check for a key
with no key material which is a) not universal since CEPH_CRYPTO_NONE
has to be excluded and b) doesn't provide much value since a smaller
than needed key is just as invalid as no key -- this has to be handled
elsewhere anyway. |
| A heap-based buffer overflow vulnerability exists in a Network management service of AOS-8 and AOS-10 that could allow an unauthenticated remote attacker to achieve remote code execution. Successful exploitation could allow an unauthenticated attacker to execute arbitrary code as a privileged user on the underlying operating system, potentially leading to a system compromise. Exploitation may also result in a denial-of-service (DoS) condition affecting the impacted system process. |
| Stack overflow vulnerability in the media platform. Impact: Successful exploitation of this vulnerability may affect availability. |
| An out-of-bounds read in power management firmware by a malicious local attacker with low privileges could potentially lead to a partial loss of confidentiality and availability. |
| A side-channel attack, which requires a physical presence to the TPM, can lead to extraction of an Elliptic Curve Diffie-Hellman (ECDH) key. |
| Improper restriction of operations within the bounds of a memory buffer in the AMD secure processer (ASP) could allow an attacker to read or write to protected memory potentially resulting in arbitrary code execution. |
| An out of bounds read in the remote management firmware could allow a privileged attacker read a limited section of memory outside of established bounds potentially resulting in loss of confidentiality or availability. |
| Unrestricted IP address binding in the AMD Device Metrics Exporter (ROCm ecosystem) could allow a remote attacker to perform unauthorized changes to the GPU configuration, potentially resulting in loss of availability |
| Improper isolation of shared resources within the CPU operation cache on Zen 2-based products could allow an attacker to corrupt instructions executed at a different privilege level, potentially resulting in privilege escalation. |
