Doc Text:
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.
