Linux Kernel OCFS2 Quota-Related Crash Vulnerability

Vulnerability

A vulnerability in the Linux kernel's OCFS2 file system can lead to a crash when the file system is mounted with quota enabled. The issue arises because certain quota-related variables are not properly initialized, causing a crash during the mounting process. This vulnerability was introduced by a commit that aimed to prevent the use of uninitialized variables in error situations, but inadvertently created a scenario where the file system could crash under specific conditions.

Impact

Mounting an OCFS2 file system with quotas enabled can lead to a system crash.
