Affected Products:
* SUSE Linux Micro 6.1
An update that solves six vulnerabilities can now be installed.
## Description:
This update for qemu fixes the following issues
* 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).
