CVE-2021-47493

CVE-2021-47493 affects the Linux kernel OCFS2 subsystem. The issue is a race between ocfs2_test_bg_bit_allocatable() and jbd2_journal_put_journal_head() that can release the journal_head from the buffer_head, when bg_bh->b_private is NULL, leading to a vmcore crash. The described impact in the...
