  "title": "freevxfs: don\u0027t BUG() on unknown typed-extent type",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  freevxfs: don\u0027t BUG() on unknown typed-extent type  vxfs_bmap_typed() handles four typed-extent types and calls BUG() in its default case, so an on-disk typed extent with any other type value crashes the kernel. It is reachable from ioctl(FIBMAP) on a regular file:    kernel BUG at fs/freevxfs/vxfs_bmap.c:230!   RIP: vxfs_bmap_typed fs/freevxfs/vxfs_bmap.c:230 [inline]        vxfs_bmap1\u002B0x128a/0x12d0 fs/freevxfs/vxfs_bmap.c:257  Replace the BUG() with WARN_ON_ONCE() and return 0 -- the value vxfs_bmap_typed() already returns on failure (and from the DEV4 case above); vxfs_getblk() maps 0 to -EIO, so the ioctl fails cleanly.",
