Details
Summary
CVE-2024-6563 is a buffer overflow vulnerability affecting Renesas arm-trusted-firmware. This issue, classified as a Classic Buffer Overflow, allows local execution of arbitrary code. The problem lies in the files <https://github.com/renesas-rcar/arm-trusted-firmware/blob/rcar_gen3_v2.5/drivers/renesas/common/io/io_rcar.C> and <https://github.com/renesas-rcar/arm-trusted-firmware/blob/rcar_gen3_v2.5/drivers/renesas/common/io/i>. In the code, the check on "addr_loaded_cnt" in line 313 is bypassed, leading to a buffer overflow at line 317. Attackers can exploit this vulnerability to manipulate the value of "addr_loaded_cnt," allowing them to control the destination and content of the write operation in line 318, effectively gaining unauthorized code execution.
