      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: chacha20poly1305 - validate poly1305 template argument\n\nchachapoly_create() still accepts the compatibility poly1305 parameter\nin the template name, but it assumes the second template argument is\nalways present and immediately passes it to strcmp().\n\nWhen the argument is missing, crypto_attr_alg_name() returns an error\npointer. Check for that before comparing the name so malformed template\ninstantiations fail with an error instead of dereferencing the error\npointer in strcmp().\n\nThis matches the surrounding Crypto API template pattern where\ncrypto_attr_alg_name() results are validated before string-specific use.",
