CVE-2022-49055 (GCVE-0-2022-49055)

Vulnerability from cvelistv5 – Published: 2025-02-26 01:54 – Updated: 2025-10-01 19:57

Title

drm/amdkfd: Check for potential null return of kmalloc_array()

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check for potential null return of kmalloc_array() As the kmalloc_array() may return null, the 'event_waiters[i].wait' would lead to null-pointer dereference. Therefore, it is better to check the return value of kmalloc_array() to avoid this confusion.

Severity ?

5.5 (Medium)
