Thore Sommer 342d130205 X.509: if signature is unsupported skip validation ... commit ef5b52a631 upstream. When the hash algorithm for the signature is not available the digest size is 0 and the signature in the certificate is marked as unsupported. When validating a self-signed certificate, this needs to be checked, because otherwise trying to validate the signature will fail with an warning: Loading compiled-in X.509 certificates WARNING: CPU: 0 PID: 1 at crypto/rsa-pkcs1pad.c:537 \ pkcs1pad_verify+0x46/0x12c ... Problem loading in-kernel X.509 certificate (-22) Signed-off-by: Thore Sommer <public@thson.de> Cc: stable@vger.kernel.org # v4.7+ Fixes: 6c2dc5ae4a ("X.509: Extract signature digest and make self-signed cert checks earlier") Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2023-09-13 09:43:03 +02:00
