krb5: krb5: Denial of Service via malformed PAC in S4U2Proxy requests

A flaw was found in krb5. This vulnerability allows a compromised or malicious cross-realm trusted Key Distribution Center KDC to cause a Denial of Service DoS. By sending an S4U2Proxy delegation request containing a malformed client name within a Privilege Attribute Certificate PAC, an attacker...

krb5: krb5: Denial of Service via crafted forwarded credentials

A flaw was found in krb5. An authenticated remote attacker can cause a Denial of Service DoS by sending specially crafted forwarded credentials containing mismatched credential entries. This improper handling triggers a null pointer dereference, causing the service to crash and become unavailable...

CVE-2026-19737
