CVE-2026-72164 ocfs2: avoid moving extents to occupied clusters

In the Linux kernel, the following vulnerability has been resolved: ocfs2: avoid moving extents to occupied clusters For non-auto OCFS2IOCMOVEEXT operations, userspace supplies a physical megoal. ocfs2moveextent initializes newphyscpos from that goal and expects ocfs2probeallocgroup to replace it...

CVE-2026-72164

CVE-2026-72164: Linux kernel OCFS2 fix for moving extents to occupied clusters. The issue occurred during non-auto OCFS2_IOC_MOVE_EXT: a probe could leave a caller-controlled goal unchanged or misreport free runs, allowing data to be written into a cluster still owned by another inode. The patch ...

CVE-2026-68442

A flaw was found in the btrfs filesystem component of the Linux kernel. When an extent map is split, a flag EXTENTFLAGLOGGING is incorrectly propagated to the new split maps. This issue occurs because the flag clearing operation was applied to the wrong variable during the splitting process...
