Improper control of a resource through its lifetime in Linux kernel - CVE-2026-23290

Published: March 25, 2026


Vulnerability identifier: #VU124567
CSH Severity: Low
CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-23290
CWE-ID: CWE-664
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper input validation in the pegasus USB driver when handling USB endpoints during device probing. A remote attacker can connect a malicious USB device with invalid or unexpected endpoint configurations to cause a denial of service.

Exploitation does not require authentication or user interaction beyond physically connecting the device; however, the attack vector is considered local due to physical access requirement.
