UBUNTU-CVE-2024-55641

In the Linux kernel, the following vulnerability has been resolved: xfs: unlock inodes when erroring out of xfs_trans_alloc_dir Debugging a filesystem patch with generic/475 caused the system to hang after observing the following sequences in dmesg: XFS (dm-0): metadata I/O error in "xfs_imap_to_bp+0x61/0xe0 [xfs]" at daddr 0x491520 len 32 error 5 XFS (dm-0): metadata I/O error in "xfs_btree_read_buf_block+0xba/0x160 [xfs]" at daddr 0x3445608 len 8 error 5 XFS (dm-0): metadata I/O error in "xfs_imap_to_bp+0x61/0xe0 [xfs]" at daddr 0x138e1c0 len 32 error 5 XFS (dm-0): log I/O error -5 XFS (dm-0): Metadata I/O Error (0x1) detected at xfs_trans_read_buf_map+0x1ea/0x4b0 [xfs] (fs/xfs/xfs_trans_buf.c:311).
