Linux Distros Unpatched Vulnerability : CVE-2026-53213

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

CVE-2026-53213

A flaw was found in the Linux kernel's drm/vc4 component. This vulnerability occurs due to incorrect handling of the krealloc function's return value. If krealloc fails and returns a null value, the original pointer to allocated memory is overwritten without proper validation, leading to a memory...

CVE-2026-53213

In the Linux kernel drm/vc4 component, CVE-2026-53213 is a memory-leak fix related to krealloc(): if krealloc() returns NULL, the original pointer may be overwritten, leaking memory. The recommended pattern is to assign krealloc() to a temporary variable, check for NULL, then update the original ...

PT-2026-52308

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak exists in the drm/vc4 component. The issue occurs when the krealloc function is used to resize a memory block and its return value is assigned directly to the original...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: The platformgetirqbyname function returns an integer. If an error occurs, platformgetirqbyname will return a negative value. Therefore, this value should be checked instead of being passed directly into...

SUSE CVE-2026-43105

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fix memory leak of BO array in hang state The hang state's BO array is allocated separately with kzalloc in vc4savehangstate but never freed in vc4freehangstate. Add the missing kfree for the BO array before freeing the...

CVE-2026-43105

A flaw was found in the drm/vc4 component of the Linux kernel. This vulnerability is due to a memory leak where the Buffer Object BO array, allocated during a hang state, is not properly freed. A local attacker could exploit this by repeatedly triggering the hang state, leading to memory exhausti...
