Live › vulnerability › CVE-2026-20566
A missing bounds check in the modem firmware allows an out-of-bounds write. A device that has connected to an attacker-controlled rogue base station, and where the attacker already holds System privilege, can be knocked offline remotely.

The flaw is in modem firmware on affected devices, and exploitation needs an attacker who already has System privilege and a rogue base station. The sources name a patch ID (MOLY01923663 / ALPS11315955) but do not map it to specific device models or versions, so whether a given phone is affected is unknown.

In Modem, there is a possible out of bounds write due to a missing bounds check. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, if a malicious actor has already obtained the System privilege. User interaction is needed for exploitation. Patch ID: MOLY01923663 / ALPS11315955; Issue ID: MSV-10866.
