An update that solves two vulnerabilities and has two security fixes can now be
installed.

## Description:

This update for qemu fixes the following issues:

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]: really fix *-virtio-gpu-pci dependency on ARM
    (bsc#1254286).
  * block/curl: fix curl internal handles handling (bsc#1252768).
