X0Urc3

**Name of the Vulnerable Software and Affected Versions** radare2 (affected versions not specified) **Description** A segmentation fault was discovered in radare2 when using the `adf` command with no or incorrect arguments. This issue arises from the `anal fcn data` function in `libr/core/cmd anal.c`, where `r anal get fcn in` returns a null pointer for `fcn`, leading to a segmentation fault later in `ensure fcn range`. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
