For the CVSS the PR:L value is used because triggering requires a local user or process with access to the relevant vcs and virtual terminal interfaces, while the exact device permissions depend on the system configuration. AC:H is used because successful triggering depends on winning a race between vcs_write and virtual console deallocation. The issue is not network reachable. Impact is at least a local denial of service through a kernel warning, Oops, or crash. Limited confidentiality or integrity impact is retained only in the paranoid score because slab reuse may affect the stale read, but no controlled write or demonstrated privilege escalation primitive is present.", "threat_severity": "Moderate"}
