Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel up to 6.10.2. This vulnerability affects an unknown function of the component mxs-dcp. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: crypto: mxs-dcp - Ensure payload is zero when using key slot We could leak stack memory through the payload field when running AES with a key from one of the hardware's key slots. Fix this by ensuring the payload field is set to 0 in such cases. This does not affect the common use case when the key is supplied from main memory via the descriptor payload.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2024-43815 since 08/17/2024. The exploitation appears to be easy. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 02/01/2026).
