CVE-2026-46073 [LOW] Linux kernel (HWE) vulnerabilities
Title: Linux kernel (HWE) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that some AMD processors did not properly clear data in
the floating point divider unit during speculative execution. A local
attacker could use this to expose sensitive information. (CVE-2025-54505)
It was discovered that some AMD Zen 2 processors did not properly isolate
shared resources in the operation cache. A local attacker could possibly
use this issue to corrupt instructions executed at a higher privilege
level, resulting in privilege escalation. (CVE-2025-54518)
It was discovered that some AMD Zen 5 processors supporting RDSEED
instruction did not properly handle entropy, potentially resulting in the
consumption of insufficiently random values. A local a

CVE-2026-53375 [HIGH] CWE-787 kernel: drm/amdgpu/vce: Prevent partial address patches
kernel: drm/amdgpu/vce: Prevent partial address patches
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/vce: Prevent partial address patches
In the case that only one of lo/hi is valid, the patching could result
in a bad address written to in FW.
A flaw was found in the Linux kernel, specifically within the drm/amdgpu/vce component responsible for video encoding. This vulnerability arises when the system attempts to update a memory address using incomplete information, where only a portion of the address is valid. This can result in data being written to an unintended memory location in the firmware, which could allow an attacker to execute unauthorized code or disrupt system operations.
