CVE-2023-53564

CVE-2023-53564 affects the OCFS2 defragmentation code in the Linux kernel. The vulnerability arises when ocfs2_move_extents and __ocfs2_move_extent incorrectly invoke journal access/dirty pairs (via ocfs2_journal_access_di and ocfs2_journal_dirty) during defragmentation, allowing a crash caused b...

The vulnerability of the ext4_split_extent_at() function in the ext4 file system of Linux kernels allows attackers to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the ext4splitextentat function in the fs/ext4/extents.c file of the Linux kernel’s file system ext4 is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibilit...
