Qemu-kvm: net: assertion failure in update_sctp_checksum()

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.44% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: qemu (Debian:13) 1:8.2.3+ds-1; qemu (openSUSE:Tumbleweed) 8.2.2-2.1; qemu-guest-agent (Red Hat:enterprise_linux:9::appstream) 17:9.0.0-10.el9_5.3.

Low priority for now. Upgrade to qemu (Debian:13) 1:8.2.3+ds-1; qemu (openSUSE:Tumbleweed) 8.2.2-2.1; qemu-guest-agent (Red Hat:enterprise_linux:9::appstream) 17:9.0.0-10.el9_5.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in QEMU. An assertion failure was present in the update_sctp_checksum() function in hw/net/net_tx_pkt.c when trying to calculate the checksum of a short-sized fragmented packet. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition.
