Summary
In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Check kzalloc return in a8xx_hfi_send_perf_table Check the return value of kzalloc() to prevent a NULL pointer dereference on allocation failure.
Patchwork: This vulnerability occurs because the `a8xx_hfi_send_perf_table` function does not properly check the return value of a memory allocation call (`kzalloc`). An attacker could potentially exploit this missing check to trigger a NULL pointer dereference, leading to a system crash and a denial of service.
Red Hat severity: not rated. Weakness: CWE-476.
Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
