Race condition in Linux kernel - CVE-2026-89860

Vulnerability identifier: #VU150433

CSH Severity: High

CVSS v4: 8.7 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-89860

CWE-ID: CWE-362

Exploitation vector: Adjecent network

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to corrupt workqueue state, causing system crashes or a looping worker.

The vulnerability exists due to a race condition in the qla2xxx NVMe abort work handling when multiple aborts are issued for the same command while its abort work item is queued. A remote attacker can trigger repeated aborts for the same command to corrupt workqueue state, causing system crashes or a looping worker.
