CVE-2026-89550
A flaw was found in the Linux kernel's SUNRPC svcauthgss module. A remote attacker could send a specially crafted Kerberos krb5 token with an insufficient length. This could lead to a division-by-zero error within the gsskrb5unwrapv2 function, resulting in a Denial of Service DoS for the affected...
CVE-2026-89550
In the Linux kernel, the following vulnerability has been resolved: SUNRPC: svcauthgss: enforce krb5 token minimum length svcauthgssunwrappriv validates only an upper bound on the wire-supplied opaque length before handing the buffer to gssunwrap: if len xdrstreamremainingxdr goto unwrapfailed;...
CVE-2026-89550
CVE-2026-89550 affects the Linux kernel in the SUNRPC svcauth_gss subsystem. The function svcauth_gss_unwrap_priv() validated only an upper bound on the wire-supplied opaque token length before passing it to the GSS unwrap path. A token with a length in the range [0, 16] passes this check and rea...
