CVE-2024-6564 1 Renesas 1 Arm-trusted-firmware 2024-11-21 6.7 Medium
Buffer overflow in "rcar_dev_init" due to using due to using untrusted data (rcar_image_number) as a loop counter before verifying it against RCAR_MAX_BL3X_IMAGE. This could lead to a full bypass of secure boot.
CVE-2024-6563 1 Renesas 1 Arm-trusted-firmware 2024-11-21 7.5 High
Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Renesas arm-trusted-firmware allows Local Execution of Code. This vulnerability is associated with program files https://github.Com/renesas-rcar/arm-trusted-firmware/blob/rcar_gen3_v2.5/drivers/renesas/common/io/i... https://github.Com/renesas-rcar/arm-trusted-firmware/blob/rcar_gen3_v2.5/drivers/renesas/common/io/io_rcar.C . In line 313 "addr_loaded_cnt" is checked not to be "CHECK_IMAGE_AREA_CNT" (5) or larger, this check does not halt the function. Immediately after (line 317) there will be an overflow in the buffer and the value of "dst" will be written to the area immediately after the buffer, which is "addr_loaded_cnt". This will allow an attacker to freely control the value of "addr_loaded_cnt" and thus control the destination of the write immediately after (line 318). The write in line 318 will then be fully controlled by said attacker, with whichever address and whichever value ("len") they desire.
CVE-2024-6287 1 Renesas 1 Rcar Gen3 2024-11-21 7.5 High
Incorrect Calculation vulnerability in Renesas arm-trusted-firmware allows Local Execution of Code. When checking whether a new image invades/overlaps with a previously loaded image the code neglects to consider a few cases. that could An attacker to bypass memory range restriction and overwrite an already loaded image partly or completely, which could result in code execution and bypass of secure boot.
CVE-2024-6285 1 Renesas 1 Rcar Gen3 2024-11-21 7.5 High
Integer Underflow (Wrap or Wraparound) vulnerability in Renesas arm-trusted-firmware. An integer underflow in image range check calculations could lead to bypassing address restrictions and loading of images to unallowed addresses.
CVE-2021-43327 1 Renesas 4 Rx65, Rx65 Firmware, Rx65n and 1 more 2024-11-21 4.6 Medium
An issue was discovered on Renesas RX65 and RX65N devices. With a VCC glitch, an attacker can extract the security ID key from the device. Then, the protected firmware can be extracted.
