| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2024-6564 | 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. | [email protected] | 6.7 | 0.01% | 2024-07-08 | 2024-11-21 |
| CVE-2024-6563 | 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) o | [email protected] | 7.5 | 0.13% | 2024-07-08 | 2024-11-21 |
| CVE-2024-6287 | 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. | [email protected] | 7.5 | 0.01% | 2024-06-24 | 2024-11-21 |
| CVE-2024-6285 | 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. | [email protected] | 7.5 | 0.01% | 2024-06-24 | 2024-11-21 |
| CVE-2024-1633 | During the secure boot, bl2 (the second stage of the bootloader) loops over images defined in the table “bl2_mem_params_descs”. For each image, the bl2 reads the image length and destination from the image’s certificate. Because of the way of reading from the image, which base on 32-bit unsigned integer value, it can result to an integer overflow. An attacker can bypass memory range restriction and write data out of buffer bounds, which could result in bypass of secure boot.
