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...
EUVD-2026-76449
In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Reject krb5 v2 wrap tokens with oversized ec field gsskrb5unwrapv2 sets buf-len to a logical length, which can be much smaller than head0.iovlen the allocated receive-page capacity. It then calls xdrbuftrim with a trim...

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...
Astra Linux – Vulnerability in krb5
In MIT Kerberos 5 also known as krb5, before version 1.21.3, an attacker could modify the plaintext Extra Count field of a confidential GSS krb5 wrap token. This modification caused the unwrapped token to appear truncated, affecting the application...
