CVE-2026-22167 GPU DDK - Cache resident PM buffers writable by other GPU requestors, leading to arbitrary write to physical memory

Software installed and run as a non-privileged user may conduct improper GPU system calls to force GPU to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel an...

CVE-2026-31694

Summary: CVE-2026-31694 fixes a Linux kernel FUSE directory-entry handling flaw. A malicious FUSE server could cause a 24-byte overflow by returning a dirent whose serialized size (based on namelen) exceeds a single PAGE_SIZE. The bug arises in fuse_add_dirent_to_cache(), which previously only ch...
