Doc Text:	A vulnerability was found in the OCFS2 filesystem in the Linux Kernel. This issue has been addressed by adding bounds checking to the ocfs2_check_dir_entry() function. This update introduces sanity checks to ensure that all members of the ocfs2_dir_entry structure remain within valid memory regions, preventing out-of-bounds memory access.	Story Points:	---
