CVE-2026-98917
Description
A flaw was found in the Linux kernel's PA-RISC architecture support. This vulnerability can lead to a Denial of Service (DoS) when deep call chains cause a kernel stack overflow on 64-bit systems. A local user executing complex or resource-intensive workloads can trigger this condition, causing the system to crash.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
