CVE-2026-80881

This Linux kernel vulnerability affects the OCFS2 (Oracle Cluster File System 2) filesystem in the ocfs2_read_blocks() function. The root cause is an incorrect assumption of exclusive ownership of buffer heads returned by sb_getblk(): when put_bh() does not drop the reference count to zero, the b...

CVE-2026-80881 ocfs2: fix buffer head management in ocfs2_read_blocks()

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix buffer head management in ocfs2readblocks In ocfs2readblocks, caller should't assume that buffer head returned by 'sbgetblk' is exclusively owned and so 'putbh' always drops bcount from 1 to 0. If it is not so, buffer...
