AI Analysis
Technical Summary
CVE-2026-46331 is a vulnerability in the Linux kernel's net/sched component, specifically in the act_pedit function, where the writable skb range per key is extended improperly. This vulnerability is addressed by a kernel security update released by Red Hat for their NVIDIA for RHEL 10 distribution. The advisory indicates a high severity impact with a CVSS vector of AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, meaning local attacker privileges are required but can lead to high impact on confidentiality, integrity, and availability. Red Hat has published an official security advisory (RHSA-2026:27709) with updated kernel packages to fix this issue.
Potential Impact
The vulnerability allows a local attacker with low privileges to potentially cause high impact on system confidentiality, integrity, and availability by exploiting the net/sched act_pedit skb writable range extension flaw. This could lead to unauthorized data access, modification, or denial of service conditions on affected systems running vulnerable kernel versions.
Mitigation Recommendations
Red Hat has released an official security update that addresses CVE-2026-46331. Users of Red Hat Enterprise Linux for NVIDIA 10 should apply the updated kernel packages as described in the Red Hat advisory RHSA-2026:27709. A system reboot is required for the update to take effect. Refer to https://access.redhat.com/articles/11258 for detailed update instructions. No additional mitigation steps are indicated beyond applying the official patch and rebooting.
