Description OSIDB Bzimport 2025-12-09 02:04:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/vmwgfx: Fix memory leak in vmw_mksstat_add_ioctl()

If the copy of the description string from userspace fails, then the page
for the instance descriptor doesn't get freed before returning -EFAULT,
which leads to a memleak.
