CVE-2026-31781

In the Linux kernel, the following vulnerability has been resolved: drm/ioc32: stop speculation on the drmcompatioctl path The drm compat ioctl path takes a user controlled pointer, and then dereferences it into a table of function pointers, the signature method of spectre problems. Fix this up b...

CVE-2026-31781

CVE-2026-31781 concerns the Linux kernel drm/ioc32 compat ioctl path, where a user-controlled pointer was used to index a table of function pointers (spectre-like pattern). The issue is mitigated by applying array_index_nospec on the index to the function-pointer list, as described in the fix. Co...
