SUSE SLED15 / SLES15 Security Update : qemu (SUSE-SU-2026:0288-1)

high Nessus Plugin ID 296664

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0288-1 advisory.

 Security issues fixed:

 - CVE-2025-12464: stack-based buffer overflow in the e1000 network device operations can be exploited by a malicious guest user to crash the QEMU process on the host (bsc#1253002).
 - CVE-2025-11234: use-after-free in WebSocket handshake operations can be exploited by a malicious client with network access to the VNC WebSocket port to cause a denial-of-service (bsc#1250984).

 Other updates and bugfixes:

 - [openSUSE][RPM] spec: require qemu-hw-display-virtio-gpu-pci for x86 too.
 - [openSUSE][RPM] spec: make glusterfs support conditional (bsc#1254494).
 - [openSUSE][RPM]: really fix *-virtio-gpu-pci dependency on ARM (bsc#1254286).
 - block/curl: fix curl internal handles handling (bsc#1252768).
 - [openSUSE][RPM] spec: qemu-vgabios is required on ppc (bsc#1230042).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
