CVE-2023-52737

CVE-2023-52737: In the Linux kernel, when using Btrfs, fiemap could deadlock with an in-flight fsync due to not taking the inode lock (i_mutex) before fiemap operations. The root cause is that fiemap_fill_next_extent() could fault while accessing user space buffers, which creates a lock-order cyc...

CVE-2023-52737 btrfs: lock the inode in shared mode before starting fiemap

In the Linux kernel, the following vulnerability has been resolved: btrfs: lock the inode in shared mode before starting fiemap Currently fiemap does not take the inode's lock VFS lock, it only locks a file range in the inode's io tree.
