CVE-2026-89550

CVE-2026-89550 is a division-by-zero vulnerability in the Linux kernel's SUNRPC svcauth_gss module. The function svcauth_gss_unwrap_priv() enforces only an upper-bound check on the wire-supplied token length, allowing tokens of 16 bytes or less (the RFC 4121 header size) to reach gss_krb5_unwrap_...

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-2026-89538 SUNRPC: Reject krb5 v2 wrap tokens with oversized ec field

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...

CVE-2026-89538

CVE-2026-89538 affects the Linux kernel's SUNRPC component, specifically the gss_krb5_unwrap_v2() function. A remote peer holding a valid GSS context can send a Kerberos v2 wrap token whose 16-bit "extra count" (ec) field exceeds the plaintext length—a structurally malformed token per RFC 4121 . ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: svcauthgss: Avoid NULL dereferencing on a zero-length gsstoken in gssreadproxyverf A zero-length gsstoken results in pageaddress being == 0, and intoken-pages0 being NULL. The code pageaddressintoken-pages0, which can lea...

CVE-2026-15567

The CVE-2026-15567 entry concerns WildFly. A remote, unauthenticated attacker can trigger an OutOfMemoryError because CSIv2Util's GSS token decoder reads an attacker-controlled length field without bounds checking and allocates a byte array of that size. This indicates a memory allocation vulnera...
