"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: make sure that WRITTEN is set on all metadata blocks\n\nWe previously would call btrfs_check_leaf() if we had the check\nintegrity code enabled, which meant that we could only run the extended\nleaf checks if we had WRITTEN set on the header flags.\n\nThis leaves a gap in our checking, because we could end up with\ncorruption on disk where WRITTEN isn\u0027t set on the leaf, and then the\nextended leaf checks don\u0027t get run which we rely on to validate all of\nthe item pointers to make sure we don\u0027t access memory outside of the\nextent buffer.\n\nHowever, since 732fab95abe2 (\"btrfs: check-integrity: remove\nCONFIG_BTRFS_FS_CHECK_INTEGRITY option\") we no longer call\nbtrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only\never call it on blocks that are being written out, and thus have WRITTEN\nset, or that are being read in, which should have WRITTEN set.\n\nAdd checks to make sure we have WRITTEN set appropriately, and then make\nsure __btrfs_check_leaf() always does the item checking. This will\nprotect us from file systems that have been corrupted and no longer have\nWRITTEN set on some of the blocks.\n\nThis was hit on a crafted image tweaking the WRITTEN bit and reported by\nKASAN as out-of-bound access in the eb accessors.
