SUSE SLES15 Security Update : qemu (SUSE-SU-2026:0043-1)

medium Nessus Plugin ID 282441

Language:

Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0043-1 advisory.

 Security issues fixed:

 - CVE-2023-1544: out-of-bounds read in VMWare's paravirtual RDMA device operations can be exploited through a malicious guest driver to crash the QEMU process on the host (bsc#1209554).
 - CVE-2024-6505: heap-based buffer overflow in the virtio-net device operations can be exploited by a malicious privileged user to crash the QEMU process on the host (bsc#1227397).
 - 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).

 Other updates and bugfixes:

 - [openSUSE][RPM] spec: require qemu-hw-display-virtio-gpu-pci for x86 too.
 - [openSUSE][RPM} spec: delete old specfile constructs.
 - block/curl: fix curl internal handles handling (bsc#1252768).
 - [openSUSE][RPM]: really fix *-virtio-gpu-pci dependency on ARM (bsc#1254286).

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.
