Local privilege escalation via Security Element integer overflow
Published Oct 30, 2023 · Updated Sep 6, 2024
Integer overflow in the Security Element API in Google Android 14 allows local users with System privileges to escalate privilege. Google has not disclosed the affected function or integer operation beyond identifying the API and resulting out-of-bounds write. Exploitation requires local System execution privileges, needs no user interaction, and can yield higher local privileges through memory corruption.
