CVE-2024-53112

Summary

CVE-2024-53112 is a vulnerability affecting the Linux kernel's OCFS2 file system. In the event that 'ioctl(OCFS2_IOC_GROUP_ADD)' fails for a specific inode, the corresponding buffer head remains cached. Subsequent calls to the same 'ioctl()' function for the same inode result in a kernel BUG in 'ocfs2_set_new_buffer_uptodate()'. To mitigate this issue, the code should be updated to uncache the buffer head using 'ocfs2_remove_from_cache()' upon encountering an error in 'ocfs2_group_add()'.
