CVE-2024-43885 Detail

Description

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix double inode unlock for direct IO sync writes If we do a direct IO sync write, at btrfs_sync_file(), and we need to skip inode logging or we get an error starting a transaction or an error when flushing delalloc, we end up unlocking the inode when we shouldn't under the 'out_release_extents' label, and then unlock it again at btrfs_direct_write(). Fix that by checking if we have to skip inode unlocking under that label.
