SUSE CVE-2025-39884
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix subvolume deletion lockup caused by inodes xarray race There is a race condition between inode eviction and inode caching that can cause a live struct btrfsinode to be missing from the root-inodes xarray. Specifically,...
