CVE-2026-9054
This vulnerability is a critical kernel panic triggered by malformed network packets. An attacker can send specially crafted TCP, IL, RUDP, or GRE packets with a length smaller than the header size, causing the kernel to crash. The crash can lead to denial of service.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
Any system whose kernel processes the affected packet types; no specific product or version is listed.
Real-world impact
An attacker could crash the kernel, causing the system to reboot or become unresponsive, effectively denying service to legitimate users.
Why this severity
The CVSS score of 9.2 reflects the high impact of a kernel panic (availability) and the ease of exploitation (network-based, no authentication).
What to do about it
No official fix or mitigation is documented in the sources yet. Monitor the vendor advisory and apply the patch as soon as it is released.
