The vulnerability of the dal_vector_reserve() function in the drivers/gpu/drm/amd/display/dc/basics/vector.c file of the Direct Rendering Infrastructure (DRI) driver for AMD graphics cards in Linux operating systems allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the dalvectorreserve function in the drivers/gpu/drm/amd/display/dc/basics/vector.c file of the Direct Rendering Infrastructure DRI driver for AMD graphics cards in Linux operating systems is related to a buffer overflow in dynamic memory. Exploiting this vulnerability could...

Unity Linux 20.1050e Security Update: kernel (UTSA-2026-102101)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-102101 advisory. In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Use kreallocarray in dalvectorreserve Why & How dalvectorreserve computes the...

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...

UBUNTU-CVE-2026-53329

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Use kreallocarray in dalvectorreserve Why & How dalvectorreserve computes the allocation size as "capacity vector-structsize" using uint32t arithmetic, which can silently wrap to a small value on overflow. This...
