"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: handle NULL b_addr in xfs_buf_free\n\nWhen xfs_buf_alloc_backing_mem() fails, xfs_buf_free() is called with\nbp->b_addr still NULL. The code falls through to the folio_put path\nwhich calls virt_to_folio(NULL), dereferencing an invalid address and\ncausing a kernel crash.\n\n Call Trace:\n xfs_buf_free+0x25f/0x510\n xfs_buf_alloc+0xc98/0x19b0\n xfs_buf_find_insert+0x55/0x14d0\n xfs_buf_get_map+0x122b/0x17c0\n xfbtree_init_leaf_block+0x11c/0x4a0\n xfbtree_init+0x1bb/0x460\n xrep_rmap_setup_scan+0x100/0x1f0\n xrep_rmapbt+0x41/0xc0\n\nFix this by skipping folio_put() when bp->b_addr is NULL."
