Technical details
The vulnerability exists in the GPU DDK (driver development kit) kernel module's handling of log2 page size parameters during physical page allocation. An unprivileged user can submit improper GPU system calls with crafted log2 page size values that bypass validation checks, causing 4K pages to be treated as higher-order pages. This leads to out-of-bounds (OOB) read and write access to memory beyond the 4K boundary. The attack vector is local, requires no special privileges, and can be triggered through GPU IOCTLs. Patches are available in updated DDK releases.
