Description
A flaw was found in the Linux kernel, specifically within the btrfs filesystem. This vulnerability, a double free, occurs in the create_space_info() function's error handling path. When an internal object initialization fails, the system attempts to release memory twice for the same resource. This can lead to system instability or a denial of service (DoS), making the system unavailable to legitimate users.
