Update to version 8.2.10.

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