CVE-2026-97545
xfs: don't leak new_bp if xfs_btree_bload_drop_buf fails
Description
In the Linux kernel, the following vulnerability has been resolved: xfs: don't leak new_bp if xfs_btree_bload_drop_buf fails LOLLM observes that in xfs_btree_bload_prep_block, xfs_btree_bload_drop_buf can hit an IO error if writing the delwri buffer list to disk fails. In this case, we fail to release new_bp, which means we lose a locked buffer. Fix that.
