CVE-2024-39478 Details
Description
In the Linux kernel, the following vulnerability has been resolved: crypto: starfive - Do not free stack buffer RSA text data uses variable length buffer allocated in software stack. Calling kfree on it causes undefined behaviour in subsequent operations.
A vulnerability has been identified in the Linux kernel's Starfive crypto driver, specifically in the RSA encryption component. This issue arises from the use of a variable-length buffer for RSA text data, which is allocated on the software stack. The vulnerability occurs because the buffer is freed using 'kfree', leading to undefined behavior in subsequent operations. This issue affects Linux kernel versions 6.7 and later.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is available in the Linux kernel stable tree.
