CriticalMetricsAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions
FreeRTOS versions prior to 10.4.3
Description
The issue is related to an integer overflow in the stream buffer.c component of the FreeRTOS kernel, which can be exploited by a remote attacker to execute arbitrary code. This is a result of a flaw in the stream buffer handling mechanism.
Recommendations
For versions prior to 10.4.3, update to version 10.4.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the stream buffer functionality to minimize the risk of exploitation.
