Mobile telephones powered by Unisoc chips are discovered to be weak to a problem that would enable attackers to remotely block communication. Cybersecurity evaluation agency Check Point Research on Thursday introduced that it recognized a vulnerability within the Unisoc modem that would impression communication. The problem exists within the modem firmware and impacts 4G and 5G Unisoc chipsets, in accordance to the agency. Unisoc acknowledged the vulnerability and regarded it of vital nature, giving a 9.4 rating out of 10.
Check Point Research stated in its report that the vital vulnerability, which is tracked as CVE-2022-20210, was found whereas scanning Non-Access Stratum (NAS) message handlers. Using a malformed packet, the difficulty might enable a hacker or a army unit to disrupt the radio communication of a tool.
The researcher at Check Point Research was ready to detect the vulnerability on the Unisoc T700 chip-based Motorola Moto G20 with the Android January 2022 safety patch. However, the difficulty is just not restricted to a specific Unisoc SoC mannequin or a selected telephone.
“We found a vulnerability in the Unisoc modem built in 11 percent of smartphones,” stated Slava Makkaveev, Reverse Engineering and Security Research lawyer at Check Point Software, in a ready assertion. “An attacker could have used a radio station to send a malformed packet that would reset the modem, depriving the user of the possibility of communication. Left unpatched, cellular communication can be blocked by an attacker.”
Makkaveev added that the vulnerability was discovered within the Unisoc modem firmware and never within the Android working system itself.
Check Point Research disclosed its findings to Unisoc in May. The Shanghai-based chipmaker acknowledged the vulnerability upon the receipt of disclosure and issued a patch.
However, the repair has not but reached customers. Google stated that it will likely be publishing the given patch within the upcoming Android Security bulletin, the analysis agency famous.
Check Point Research urges customers to at all times replace their cellphones to the newest software program model out there.
Unisoc, beforehand referred to as Spreadtrum, has been getting larger out there of smartphone chipmakers for the previous few months.
According to a latest report by market analysis agency Counterpoint, the share of Unisoc grew to 47 p.c within the first quarter of the yr from 20 p.c in the identical quarter final yr. It additionally gave a tricky battle to MediaTek that struggled with provide constraints for 4G chips.
