Security Bulletin

This security bulletin contains information about 10 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU77990

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-21255

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local application to escalate privileges on the system.

The vulnerability exists due to insufficient validation of user-supplied input within the binder_transaction_buffer_release() function in Binder subsystem in Android kernel. A local application can trigger a use-after-fee error and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.
