Race condition in Linux kernel - CVE-2022-44033

Vulnerability identifier: #VU77324

CSH Severity: Low

CVSS v4: 7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-44033

CWE-ID: CWE-362

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows an attacker to escalate privileges on the system.

The vulnerability exists due to a race condition in drivers/char/pcmcia/cm4040_cs.c in Linux kernel. An attacker with physical access to device can remove the PCMCIA device while calling open() to trigger a use-after-free error and execute arbitrary code on the system.
