VAR-202110-0167

Vulnerability from variot - Updated: 2023-12-24 22:51

Lack of boundary checking of a buffer in set_skb_priv() of modem interface driver prior to SMR Oct-2021 Release 1 allows OOB read and it results in arbitrary code execution by dereference of invalid function pointer. The Samsung OOB driver is a driver that reads the modem interface for Samsung mobile devices.

The Samsung OOB read modem interface driver has an out-of-bounds read vulnerability. An attacker can exploit this vulnerability to execute arbitrary code
