Vulnerability from github – Published: 2024-05-03 03:30 – Updated: 2024-05-03 03:30

Details

The specific flaw exists within the handling of command 0x422 provided to the tmpServer service. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-19905.

Severity ?

6.8 (Medium)
