Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver allows a local non-privileged user to make improper memory processing operations to exploit a software race condition. If the system’s memory is carefully prepared by the user, then this in turn cause a use-after-free.This issue affects Bifrost GPU Kernel Driver: from r35p0 through r40p0; Valhall GPU Kernel Driver: from r35p0 through r40p0.
