EUVDB-ID: #VU95764

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2005-3055

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local user to perform service disruption.

Linux kernel 2.6.8 to 2.6.14-rc2 allows local users to cause a denial of service (kernel OOPS) via a userspace process that issues a USB Request Block (URB) to a USB device and terminates before the URB is finished, which leads to a stale pointer reference.

Mitigation

Install update from vendor's repository.

Vulnerable software versions

Linux kernel: All versions
