Description

A flaw was found in the Linux kernel's drm/msm/a6xx component. 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.

Mitigation

No mitigation is specified in collected source.
