CVE-2026-57965: Integer Overflow or Wraparound in Red Hat Red Hat Enterprise Linux 10
A flaw was found in spice-vdagent. A malicious or compromised SPICE host can trigger an integer overflow by sending a specially crafted message. This vulnerability can lead to a heap buffer overflow, causing the spice-vdagent daemon to crash and resulting in a Denial of Service (DoS) for the virtual machine. This issue requires the SPICE host to be untrusted or compromised for exploitation.
AI Analysis
Technical Summary
The vulnerability in spice-vdagent allows an attacker controlling or compromising the SPICE host to trigger an integer overflow by sending a crafted message. This overflow leads to a heap buffer overflow, crashing the spice-vdagent daemon and causing a denial of service on the virtual machine running Red Hat Enterprise Linux 10. The attack vector is local to the SPICE host, requiring high privileges on that host. No confidentiality impact is indicated, but integrity is impacted and availability is severely affected due to the DoS.
Potential Impact
Successful exploitation causes the spice-vdagent daemon to crash, resulting in denial of service for the virtual machine. There is no reported impact on confidentiality, but integrity is affected due to the integer overflow. Availability is high impacted because the virtual machine becomes unresponsive or unusable until the daemon is restored.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-57965 for current remediation guidance. Until a fix is available, ensure that the SPICE host is trusted and secure to prevent exploitation. No official fix or temporary workaround is currently documented in the provided advisory content.
