CVE-2024-7547

oFono SMS Decoder Stack-based Buffer Overflow Privilege Escalation
Vulnerability. This vulnerability allows local attackers to execute
arbitrary code on affected installations of oFono. An attacker must first
obtain the ability to execute code on the target modem in order to exploit
this vulnerability.
The specific flaw exists within the parsing of SMS PDUs. The issue results
from the lack of proper validation of the length of user-supplied data
prior to copying it to a stack-based buffer. An attacker can leverage this
vulnerability to execute code in the context of the service account. Was
ZDI-CAN-23460.
