CVE-2022-50839

Summary (CVE-2022-50839) The issue is in the Linux kernel’s jbd2 journaling subsystem. When a buffer isn’t uptodate, jbd2_fc_wait_bufs returns -EIO without updating journal->j_fc_off, and jbd2_fc_release_bufs may release the buffer head from j_fc_off - 1 if bh is NULL, causing a buffer head re...
