"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: reject zero bd_oblocknr in nilfs_ioctl_mark_blocks_dirty()\n\nnilfs_ioctl_mark_blocks_dirty() uses bd_oblocknr to detect dead blocks\nby comparing it with the current block number bd_blocknr. If they differ,\nthe block is considered dead and skipped.\n\nHowever, bd_oblocknr should never be 0 since block 0 typically stores the\nprimary superblock and is never a valid GC target block. A corrupted ioctl\nrequest with bd_oblocknr set to 0 causes the comparison to incorrectly\nmatch when the lookup returns -ENOENT and sets bd_blocknr to 0, bypassing\nthe dead block check and calling nilfs_bmap_mark() on a non-existent\nblock. This causes nilfs_btree_do_lookup() to return -ENOENT, triggering\nthe WARN_ON(ret == -ENOENT).\n\nFix this by rejecting ioctl requests with bd_oblocknr set to 0 at the\nbeginning of each iteration.\n\n[ryusuke: slightly modified the commit message and comments for accuracy]"
