CVE-2026-31781
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
drm/ioc32: stop speculation on the drm_compat_ioctl 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 by calling array_index_nospec() on the
index to the function pointer list.
