Android security bugs could be exploited by an attacker to elevate their privileges and gain access to sensitive information on affected devices. They can also lead to a denial of service on the affected devices.

These vulnerabilities exist due to flaws in the software framework. They have been detected in the multimedia framework, system kernel and kernel components. Security bugs have also been detected in Imagination Technologies components, MediaTek components, UNISOC components, Qualcomm components, and closed-source components.

Security bug details were also shared by Android in their security bulletin while asking users to update their software. The CERT-In report flagged Android OS versions 10, 11, 12, 12L, and 13 for these security bugs.

Google Chrome operating system

Chrome OS security bugs were exploited by bypassing security restrictions, which executed arbitrary code and caused denial of service on affected systems. CERT-In said these bugs could be exploited by sending specially crafted requests.

The security flaws were found after using free network service like WebSQL, Sign-In Flow, Input and SplitScreen.

Bugs have also been reported due to improper implementation in Chrome OS’s site isolation and lock screen; heap buffer overflow in internals, screen capture, exosphere, Ash and WebUI. Insufficient validation of untrusted inputs in DevTools has also been observed.

Google released Long Term Channel Updates to address these security bugs, which were reported in Chrome OS LTS channel versions prior to 102.
