Vulnerability identifier: #VU68339

Vulnerability risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-41848

CWE-ID: CWE-362

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Linux kernel
Operating systems & Components / Operating system

Vendor: Linux Foundation

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a race condition in the drivers/char/pcmcia/synclink_cs.c in the Linux kernel. An attacker with physical proximity to the affected system can remove a PCMCIA device while calling ioctl, cause a race condition between mgslpc_ioctl and mgslpc_detach and perform a denial of service (DoS) attack.

Mitigation
Install updates from vendor's website.
