The issue is related to the `tomoyo mount acl` function in the Linux kernel, which calls the `kern path` function with arguments taken directly from a mount system call. This allows local users to cause a denial of service (OOPS) or possibly have unspecified other impact via a NULL value for the device name.

The issue allows local users to obtain sensitive information or cause a denial of service. This is due to the proc filesystem implementation not restricting access to the /proc directory tree of a process after it performs an exec of a setuid program, enabling the use of open, lseek, read, and write system calls.

Name of the Vulnerable Software and Affected Versions: Linux kernel versions 2.6 up to 2.6.18-stable Description: The issue in the seqfile handling, specifically the ip6fl get n function in ip6 flowlabel.c, allows local users to cause a denial of service, resulting in a system hang or oops, by triggering an infinite loop while searching for flowlabels through unspecified manipulations. Recommendations: For Linux kernel versions 2.6 up to 2.6.18-stable, consider applying a patch that fixes the infinite loop issue in the ip6fl get n function to prevent denial of service attacks.
