CVE-2024-57806

CVE-2024-57806 relates to a Linux kernel btrfs quota (SIMPLE_QUOTA) atomicity bug. The fix ensures the BTRFS_FEATURE_INCOMPAT_SIMPLE_QUOTA flag is set immediately after enabling SIMPLE_MODE, so both the quota status flag and the incompat flag are flushed in the same transaction. Without this, a s...
