SO-AND-SO reports:

When issuing a ticket for a TGS renew or validate request, copy only the server field from the outer part of the header ticket to the new ticket. Copying the whole structure causes the enc_part pointer to be aliased to the header ticket until krb5_encrypt_tkt_part() is called, resulting in a double-free if handle_authdata() fails..

MIT reports:

CVE-2017-11368:

In MIT krb5 1.7 and later, an authenticated attacker can cause an assertion failure in krb5kdc by sending an invalid S4U2Self or S4U2Proxy request.

CVE-2017-11462:

RFC 2744 permits a GSS-API implementation to delete an existing security context on a second or subsequent call to gss_init_sec_context() or gss_accept_sec_context() if the call results in an error. This API behavior has been found to be dangerous, leading to the possibility of memory errors in some callers. For safety, GSS-API implementations should instead preserve existing security contexts on error until the caller deletes them.

All versions of MIT krb5 prior to this change may delete acceptor contexts on error. Versions 1.13.4 through 1.13.7, 1.14.1 through 1.14.5, and 1.15 through 1.15.1 may also delete initiator contexts on error.

MITKRB5-SA-2022-001 Vulnerabilities in PAC parsing:

Due to an integer overflow vulnerabilities in PAC parsing An authenticated attacker may be able to cause a KDC or kadmind process to crash by reading beyond the bounds of allocated memory, creating a denial of service.

On 32-bit platforms an authenticated attacker may be able to cause heap corruption resulting in an RCE.
