Linux Kernel OCFS2 Symlink Read Error Handling Vulnerability

A vulnerability in the Linux kernel's OCFS2 file system has been addressed. The issue arose from improper handling of symlink read errors. The original patch, which contained some bugs, was revised and split into individual patches for clarity and accuracy. The final patch ensures that if the buffer cannot be read, the page is unlocked before returning, thus preventing potential resource leaks.

Impact

The vulnerability could lead to improper error handling, potentially causing resource management issues such as memory leaks.
