Vulnerability details
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to an out-of-bounds read in the firmware log buffer handling in drivers/accel/ivpu/ivpu_fw_log.c when processing firmware-supplied log indices. A local user can supply invalid read or write indices to trigger out-of-bounds buffer access and cause a denial of service.
Exploitation requires firmware to provide invalid log buffer index values.
