Name of the Vulnerable Software and Affected Versions:
Linux kernel versions 2.5.12 through 2.6.8
Description:
The issue is related to a deadlock bug in the Linux kernel's sysv filesystem. The problem occurs when
sb bread() is called with pointers lock held, leading to a "write lock(&pointers lock) => read lock(&pointers lock) deadlock" bug. This bug was introduced in Linux 2.5.12 and partially fixed in Linux 2.6.8, but the fix introduced another bug. The vulnerability can cause a denial of service.Recommendations:
To resolve the issue, update the Linux kernel to a version that includes the fix for the sysv filesystem deadlock bug.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
