kernel: drm/amd/display: Clamp VBIOS HDMI retimer register count to array size

A flaw was found in the Linux kernel's AMD display driver. This vulnerability occurs when the driver processes malformed VBIOS Video Basic Input/Output System data. Specifically, unvalidated register counts in the VBIOS can lead to an out-of-bounds memory write during the driver's initialization...

kernel: drm/amd/display: Use krealloc_array() in dal_vector_reserve()

A flaw was found in the Linux kernel's drm/amd/display component. The dalvectorreserve function calculates memory allocation size using 32-bit arithmetic, which can lead to an integer overflow. This overflow causes a smaller memory buffer to be allocated than intended, resulting in a heap overflo...

kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation

A flaw was found in the Linux kernel's AMD display component. This vulnerability arises from incorrect validation of display mode changes during Display Stream Compression DSC processing. A local attacker could exploit this by initiating specific display configuration changes, which may lead to a...

kernel: xen: AMD Zen 2 Processors: Privilege escalation via improper CPU cache isolation

A flaw was found in AMD Zen 2-based processors, affecting components such as the kernel and Xen hypervisor. Improper isolation of shared resources within the CPU operation cache could allow an attacker to corrupt instructions executed at a different privilege level. This could potentially result ...
