+From: Helmut Grohne <helmut@...divi.de>
+Subject: [PATCH v3] CVE-2022-45142: gsskrb5: fix accidental logic inversions
+
+The referenced commit attempted to fix miscompilations with gcc-9 and
+gcc-10 by changing `memcmp(...)` to `memcmp(...) != 0`. Unfortunately,
+it also inverted the result of the comparison in two occasions. This
+inversion happened during backporting the patch to 7.7.1 and 7.8.0.
+
+Fixes: f6edaafcfefd ("gsskrb5: CVE-2022-3437 Use constant-time memcmp()
+ for arcfour unwrap")
+Signed-off-by: Helmut Grohne <helmut@...divi.de>
