There is no fixed version for torvalds/linux.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.
