Vulnerability of services for the NFS ONCRPC XDR driver on Windows operating systems, allowing a hacker to execute arbitrary code

The vulnerability of services for the NFS ONCRPC XDR driver on Windows operating systems is related to the use of memory after it is freed. Exploiting this vulnerability allows a remote attacker to execute arbitrary code...

Astra Linux – Vulnerability in krb5

The file “lib/kadm5/kadmrpcxdr.c” in MIT Kerberos 5 also known as krb5 before versions 1.20.2 and 1.21.x before version 1.21.1 exposes an uninitialized pointer. A remotely authenticated user can cause a Kadmind crash. This occurs because the function xdrkadm5principalentrec does not validate the...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: NFSD: The encoder for NFSv2 GETACL results has been completed. The xdrstream conversion inadvertently left some code that set the pagelen of the send buffer. The XDR stream encoders should now handle this automatically. This...

The vulnerability in the virtual machine of the cloud security platform Palo Alto Networks Cortex XDR Broker VM allows a attacker to execute arbitrary code.

The vulnerability of the virtual machine on Palo Alto Networks’ Cortex XDR Broker VM for cloud security platforms is related to the implementation or modification of arguments. Exploiting this vulnerability allows a malicious actor to execute arbitrary code remotely...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - SUNRPC: fix gssxdecoptionarray error path bugs Four coupled defects in the gssx XDR option-array decoder make the error paths unsafe: a NULL deref in the caller...

CVE-2026-89674

A flaw was found in the nfsd component of the Linux kernel. Incorrect calculations in the XDR External Data Representation buffer size within the nfsd4ffencodelayoutget function can lead to two critical issues. An attacker could potentially exploit this to write data beyond the intended memory...

CVE-2026-89673

A flaw was found in the Linux kernel's NFS daemon nfsd. A remote attacker could exploit an error in the XDR External Data Representation padding calculation within the ffencodegetdeviceinfo function. This mismatch between reserved and actual data size leads to the leakage of stale reply-page...

CVE-2026-89544

A flaw was found in the Linux kernel's SUNRPC component. Multiple defects in the gssxdecoptionarray XDR option-array decoder's error handling can lead to a NULL dereference, a reference count leak, and a use-after-free vulnerability. An attacker could potentially exploit these issues by providing...
