CVE-2022-48463

Local service interruption via unchecked buffer copy

Published Dec 4, 2023 · Updated Aug 3, 2024

Out-of-bounds write in the Wi-Fi service on affected UNISOC Android devices allows local users to interrupt the service with crafted input. The Wi-Fi service fails to check an input boundary before copying data, allowing the write to exceed the destination buffer. The vendor description requires no additional execution privileges, while its CVSS assessment marks high privileges; only denial of service is documented.
