Security Bulletin
This security bulletin contains information about 13 vulnerabilities.
EUVDB-ID: #VU63652
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-2020-25670
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the NFC LLCP protocol implementation. A local user can perform manipulation with an unknown input for the llcp_sock_bind() function to crash or escalate their privileges on the system.
MitigationUpdate the affected package linux to the latest version.
