CVE-2025-40014

一、漏洞信息
漏洞编号：CVE-2025-40014
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.4.0,6.6.0
CVSS V3.0分值：
BaseScore：7.8 High
Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:objtool, spi: amd: Fix out-of-bounds stack access in amd_set_spi_freq()If speed_hz < AMD_SPI_MIN_HZ, amd_set_spi_freq() iterates over theentire amd_spi_freq array without breaking out early, causing i to gobeyond the array bounds.Fix that by stopping the loop when it gets to the last entry, so the lowspeed_hz value gets clamped up to AMD_SPI_MIN_HZ.Fixes the following warning with an UBSAN kernel: drivers/spi/spi-amd.o: error: objtool: amd_set_spi_freq() falls through to next function amd_spi_set_opcode()

CVE-2025-40014

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

objtool, spi: amd: Fix out-of-bounds stack access in amd_set_spi_freq()

If speed_hz < AMD_SPI_MIN_HZ, amd_set_spi_freq() iterates over the
entire amd_spi_freq array without breaking out early, causing 'i' to go
beyond the array bounds.

Fix that by stopping the loop when it gets to the last entry, so the low
speed_hz value gets clamped up to AMD_SPI_MIN_HZ.

Fixes the following warning with an UBSAN kernel:

drivers/spi/spi-amd.o: error: objtool: amd_set_spi_freq() falls through to next function amd_spi_set_opcode()

The Linux kernel CVE team has assigned CVE-2025-40014 to this issue.
