  "details": "In the Linux kernel, the following vulnerability has been resolved:  ocfs2: avoid moving extents to occupied clusters  For non-auto OCFS2_IOC_MOVE_EXT operations, userspace supplies a physical me_goal.  ocfs2_move_extent() initializes new_phys_cpos from that goal and expects ocfs2_probe_alloc_group() to replace it with a free run in the target block group.  The probe currently leaves *phys_cpos unchanged if the scan reaches the end of the group without finding a free run.  An occupied goal at the last bit can therefore survive the probe and be passed to __ocfs2_move_extent(), which copies file data into a cluster still owned by another inode before the bitmap is updated.  When the probe does find a free run, it also subtracts move_len from the ending bit.  The start of an N-bit run ending at i is i - N + 1, so the current calculation can report the bit immediately before the free run.  Clear *phys_cpos before scanning and use the correct free-run start.  Callers already treat a zero result as -ENOSPC, so failed probes no longer continue with an occupied caller-controlled goal.",
