Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU61181

Risk: Low

CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2022-0487

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to a use-after-free error in rtsx_usb_ms_drv_remove in drivers/memstick/host/rtsx_usb_ms.c in memstick in the Linux kernel. A local user can trigger a use-after-free error and gain access to sensitive information.

Mitigation

Install updates from vendor's repository.
