Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: btrfs: The release path occurs before igetfailed in btrfsreadlocked inode. In btrfsreadlocked inode, if we fail to look up the inode, we jump to the ‘out’ label with a path that has a read-locked leaf. Then, we call igetfailed...

CVE-2026-23018

CVE-2026-23018 describes a Linux kernel vulnerability in the btrfs code path. In btrfs_read_locked_inode(), a path with a read-locked leaf from a subvolume tree is used while calling btrfs_init_file_extent_tree(), which may perform GFP_KERNEL allocations and trigger memory reclaim. This can creat...
