CVE-2022-20122
The PowerVR GPU driver allows unprivileged apps to allocated pinned memory, unpin it (which makes it available to be freed), and continue using the page in GPU calls.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
