This security bulletin contains information about 2 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU63318

Risk: Low

CVSSv4.0: 4.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-26966

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to a use-after-free error in drivers/net/usb/sr9700.c in the Linux kernel. A remote attacker can pass specially crafted data and obtain sensitive information from heap memory.

Mitigation

Install updates from vendor's repository.
