<p>An update that solves six vulnerabilities can now be installed.</p>
<h2>Description:</h2>
<p>This update for qemu fixes the following issues</p>
<ul>
<li>CVE-2025-14876: qemu-kvm: Unbounded allocation in virtio-crypto (bsc#1255400).</li>
<li>CVE-2026-0665: out-of-bounds heap access can lead to a denial of service or potential memory corruption (bsc#1256484).</li>
<li>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).</li>
<li>CVE-2026-3195: heap buffer overflow when reading input audio in the virtio-snd device input callback due to
insufficient checks in <code>virtio_snd_pcm_in_cb</code> (bsc#1259080).</li>
<li>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).</li>
<li>CVE-2026-3842: hyperv/syndbg: missing mapped-length guard after cpu_physical_memory_map causes host OOB write
(bsc#1262089).</li>
</ul>
