CVE-2021-25394

CVSS 6.4 MEDIUMEPSS 0.4%● KEVCWE-416
In short

The MFC charger driver has a bug where it tries to use memory that has already been freed, caused by a timing issue. If an attacker gains radio-level access to the device, they could exploit this to write data anywhere in memory.

Technical detail

A use-after-free vulnerability in the MFC charger driver (pre-SMR MAY-2021 Release 1) arises from a race condition in memory management. Exploitation requires compromise of radio privileges and allows arbitrary memory writes; this could lead to privilege escalation or system compromise depending on the context of the write operation.

Summary generated and translated by AI from the official description.
A use after free vulnerability via race condition in MFC charger driver prior to SMR MAY-2021 Release 1 allows arbitrary write given a radio privilege is compromised.
