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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
