SUSE SLES15 Security Update : qemu (SUSE-SU-2026:2386-1)

medium Nessus Plugin ID 321014

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-2026:2386-1 advisory.

 - CVE-2025-14876: qemu-kvm: Unbounded allocation in virtio-crypto (bsc#1255400).
 - CVE-2026-0665: out-of-bounds heap access can lead to a denial of service or potential memory corruption (bsc#1256484).
 - CVE-2026-2243: incorrect bounds check leads to heap out-of-bounds read and a 12-byte information leak when processing specially crafted VMDK files (bsc#1258509).
 - CVE-2026-3195: heap buffer overflow when reading input audio in the virtio-snd device input callback due to insufficient checks in `virtio_snd_pcm_in_cb` (bsc#1259080).
 - CVE-2026-3196: integer overflow in the virtio-snd device via PCM_INFO requests from the guest leads to unbounded memory allocation and host denial-of-service (bsc#1259079).
 - CVE-2026-3842: hyperv/syndbg: missing mapped-length guard after cpu_physical_memory_map causes host OOB write (bsc#1262089).

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.
