Race condition in Linux kernel - CVE-2026-90430

Vulnerability identifier: #VU151054

CSH Severity: Low

CVSS v4: 5.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-90430

CWE-ID: CWE-362

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a race condition in the Tegra241 CMDQV LVCMDQ initialization and error-handling logic when an error interrupt is handled while an LVCMDQ is being initialized. A local user can cause an LVCMDQ error to be handled during initialization to cause a denial of service.

The condition can occur when an LVCMDQ error is inherited across a kexec.
