The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding β€œ!= 0” comparisons to the result of memcmp. When these patches were backported a logic inversion sneaked in causing the validation of message integrity codes in gssapi/arcfour to be inverted. (CVE-2022-45142)
