CVE-2026-98814
Description
A flaw was found in the Linux kernel's Non-Volatile Memory Express (NVMe) driver. A local attacker can cause a denial of service (DoS) or potentially escalate privileges by exploiting a use-after-free flaw. This issue occurs when an input/output (I/O) passthrough command is sent through a multipath storage device after the initial controller path has been removed, causing the kernel to access already-freed memory.
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.
