FreeRDP: FreeRDP: Out-of-bounds memory access in Kerberos decryption

A flaw in FreeRDP's Kerberos implementation allows a malicious RDP peer to cause an out-of-bounds memory access by providing an unbounded GSS Wrap-token EC field. This occurs during CredSSP/NLA decryption and can lead to a denial of service or information disclosure...

CVE-2026-89538

A flaw was found in the Linux kernel's Server Unix Remote Procedure Call SUNRPC component. A remote attacker, with a valid Generic Security Service GSS context, could send a specially crafted Kerberos v2 wrap token with an oversized "extra count" ec field. This improper handling of malformed toke...
