"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nasymmetric_keys: reject trust keys without IDs\n\nThe PKCS#8 parser deliberately leaves the asym_key_ids payload slot\nempty. key_or_keyring_common() unconditionally dereferences that slot\nwhen a PKCS#8 key is supplied to a key_or_keyring restriction. Both the\nplain and :chain forms reach this branch, allowing an unprivileged caller\nto trigger a NULL pointer dereference through KEYCTL_RESTRICT_KEYRING\nfollowed by add_key().\n\n Oops: general protection fault, probably for non-canonical address 0xdffffc0000000000\n KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\n RIP: 0010:key_or_keyring_common (crypto/asymmetric_keys/restrict.c:205 crypto/asymmetric_keys/restrict.c:279)\n Call Trace:\n <TASK>\n __key_create_or_update (security/keys/key.c:884)\n key_create_or_update (security/keys/key.c:1021)\n __do_sys_add_key (security/keys/keyctl.c:134)\n do_syscall_64 (arch/x86/entry/common.c:52 arch/x86/entry/common.c:83)\n entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130)\n </TASK>\n Kernel panic - not syncing: Fatal exception\n\nReject an asymmetric restriction key without key IDs.
