administrator, a condition an unprivileged attacker cannot create.\nPR:L - On systems with dmesg_restrict disabled, an ordinary local user can read the global kernel log and can invoke the affected callbacks through AF_ALG without capabilities.\nUI:N - No victim action is required after the vulnerable logging configuration is active; services and protocol stacks install keys during normal operation.\nS:U - The disclosure and resulting compromise of kernel-protected cryptographic sessions remain within the host kernel's security authority.\nC:H - The dumps contain complete encryption and authentication keys, including RFC4106/RFC4543 salt material, enabling decryption of protected IPsec, SMB, or other traffic.\nI:H - Disclosed AEAD or authentication keys permit valid ciphertexts
