The vulnerability of the `btrfs_get_or_create_delayed_node()` function in the `fs/btrfs/delayed-inode.c` file of the Linux kernel’s filesystem module allows a attacker to cause a service failure.

The vulnerability of the btrfsgetorcreatedelayednode function in the fs/btrfs/delayed-inode.c file of the Linux kernel’s filesystem module is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to trigger a service failure...

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...
