"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfreevxfs: don't BUG() on unknown typed-extent type\n\nvxfs_bmap_typed() handles four typed-extent types and calls BUG() in\nits default case, so an on-disk typed extent with any other type value\ncrashes the kernel. It is reachable from ioctl(FIBMAP) on a regular\nfile:\n\n kernel BUG at fs/freevxfs/vxfs_bmap.c:230!\n RIP: vxfs_bmap_typed fs/freevxfs/vxfs_bmap.c:230 [inline]\n vxfs_bmap1+0x128a/0x12d0 fs/freevxfs/vxfs_bmap.c:257\n\nReplace the BUG() with WARN_ON_ONCE() and return 0 -- the value\nvxfs_bmap_typed() already returns on failure (and from the DEV4 case\nabove); vxfs_getblk() maps 0 to -EIO, so the ioctl fails cleanly."
