Local GPU memory corruption via dangling page-table entries
Published Jun 19, 2026 · Updated Jun 19, 2026
Use-after-free in affected Imagination Technologies Graphics DDK releases through 25.3 RTM allows local users to corrupt GPU page tables. The _MMU_AllocLevel error path frees backing physical memory without first cleaning GPU page-table objects, leaving dangling entries that reuse freed pages. A non-privileged local process must issue improper GPU system calls; successful triggering permits kernel-context memory corruption and service interruption.
