In the Linux kernel, the following vulnerability has been resolved:

vfio/platform: check the bounds of read/write syscalls

count and offset are passed from user space and not checked, only offset is capped to 40 bits, which can be used to read/write out of bounds of the device.

ICSA-25-226-07 — Siemens Third-Party Components in SINEC OS

nfsd: NULL dereference in nfs3svc_encode_getaclres. scsi: core: use-after-free vulnerability. NFSD: vulnerability caused by loff_t overflow on the server when a client reads near the maximum offset, causing the server to return an EINVAL error, which the client retries indefinitely, instead of handling out-of-range READ requests by returning a short result with an EOF flag. NFSD: Vulnerability caused by an underflow in ia_size due to a mismatch between signed and unsigned 64-bit file size values, which can cause issues when handling large file sizes from NFS clients. NFSD: Vulnerability handling large file sizes for NFSv3 improperly capping client size values larger than s64_max, leading to unexpected behavior and potential data corruption. sh: cpuinfo: warning for CONFIG_CPUMASK_OFFSTACK. When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected, cpu_max_bits_warn() generates a runtime warning when showing /proc/cpuinfo. A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables.

The default behavior when the stack-protector detects an overflow is to terminate your application, resulting…

OESA-2025-1336 — kernel security update

Affected: openEuler:20.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

drm/plane: Move range check for format_count earlier

While the check for format_count > 64 in __drm_universal_plane_init() shouldn't be hit (it's a WARN_ON), in its current position it will then leak the plane->format_types array and fail to call drm_mode_object_unregister() leaking the modeset identifier. Move it to the start of the function to avoid allocating those resources in the first place.(CVE-2021-47659)

In the Linux kernel, the following vulnerability has been resolved:

scsi: target: tcmu: Fix possible page UAF

tcmu_try_get_data_page() looks up pages under cmdr_lock, but it does not take refcount properly and just returns page pointer. When tcmu_try_get_data_page() returns, the returned page may have been freed by tcmu_blocks_release().

We need to get_page() under cmdr_lock to avoid concurrent tcmu_blocks_release().(CVE-2022-49053)

In the Linux kernel, the following vulnerability has been resolved:

ASoC: atmel: Add missing of_node_put() in at91sam9g20ek_audio_probe

This node pointer is returned by of_parse_phandle() with refcount incremented in this function. Calling of_node_put() to avoid the refcount leak.(CVE-2022-49243)

In the Linux kernel, the following vulnerability has been resolved:
