Name of the Vulnerable Software and Affected Versions merbanan/rtl 433 versions up to and including 25.02 and prior to commit 25e47f8

Description The software contains a stack-based buffer overflow in the parse rfraw() function, located in src/rfraw.c. Processing crafted or excessively large raw RF input data can cause the application to write beyond the bounds of a stack buffer, leading to memory corruption or a crash. This can result in a denial of service and, potentially, further exploitation depending on the environment.

Recommendations Update to a version after commit 25e47f8.
