Summary
Security update for libvirt
Details

This update for libvirt fixes the following issues:

  • CVE-2026-18917: integer overflow in NodeGetFreePages RPC handler leads to heap buffer overflow and allows for possible local privilege escalation (bsc#1275863).
  • CVE-2026-61477: newline injection in network XML DNS TXT/SRV fields allows for dnsmasq configuration directive injection and can lead to arbitrary code execution as root (bsc#1274576).
  • CVE-2026-63622: symlink-following in virFileChownFiles() allows swtpm user to trick the root-level libvirt daemon into changing the ownership of an arbitrary file and can lead to privilege escalation (bsc#1275264).
  • CVE-2026-63623: newly created volume images are temporarily world-readable during clone/convert operations, which can lead to sensitive information disclosure (bsc#1275265).
  • CVE-2026-77159: root chown() on swtpm logfile follows symlinks and allows for root-owned file ownership changes, which can lead to privilege escalation (bsc#1274946).
