CVE-2026-80624— mfd: cs42l43: Sanity check firmware size

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： mfd: cs42l43: 对固件大小进行健全性检查 当前代码仅检查是否接收到了固件，但并未验证固件大小是否大于固件头（firmware header）的大小。由于固件指针被解引用为指向头结构体的指针，这可能导致越界内存访问（out-of-bounds memory access）。因此，添加缺失的检查。

Vulnerability Title
mfd: cs42l43: Sanity check firmware size
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: mfd: cs42l43: Sanity check firmware size Currently the code checks if a firmware was received, however it does not verify that the firmware size is larger than the firmware header. As the firmware pointer is dereferenced as a pointer to the header structure this could lead to an out of bounds memory access. Add the missing check.
