The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098886 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...

CVE-2026-53329 drm/amd/display: Use krealloc_array() in dal_vector_reserve()

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...

CVE-2026-53329: Uncontrolled Recursion

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...

CVE-2026-53213: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: fix krealloc memory leak Don't just overwrite the original pointer passed to krealloc with its return value without checking latter: MEM = kreallocMEM, SZ, GFP; If krealloc returns NULL, that erases the pointer to the...

CVE-2023-53181: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking on krealloc failure Currently dmaresvgetfences will leak the previously allocated array if the fence iteration got restarted and the kreallocarray fails. Free the old array by hand, and make sure we...

CVE-2021-47305

In the Linux kernel, the following vulnerability has been resolved: dma-buf/syncfile: Don't leak fences on merge failure Each addfence call does a dmafenceget on the relevant fence. In the error path, we weren't calling dmafenceput so all those fences got leaked. Also, in the kreallocarray failur...
