CVE-2023-53081

CVE-2023-53081 affects the Linux kernel’s ocfs2 function. When a buffered write fails to copy data into the page cache, ocfs2_write_end_nolock() zeroes the page and dirties it, which can leave a dirty page beyond EOF. If writeback occurs before i_size is expanded, the page can reach an inconsiste...
