VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: A use-after-free (UAF) issue exists in the proc file system. A direct check of pde->proc ops->proc lseek may lead to a UAF condition during a rmmod scenario. This is due to a gap in proc reg open() following a previous fix related to proc get inode().
