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. This however can lead to a deadlock if we have a concurrent...

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-2021-47072

CVE-2021-47072 (Linux kernel, btrfs) : The vulnerability concerns the btrfs filesystem where, after moving an inode between directories and logging both old and new dentries, a power-failure can leave the old dentry present when only the new one should exist. The bug occurs because the old parent...
