Detailsinfo

A vulnerability was found in Linux Kernel up to 6.6.22/6.7.10/6.8.1. It has been classified as problematic. Affected is the function clk_mt8135_apmixed_probe of the component mediatek. The manipulation with an unknown input leads to a double free vulnerability. CWE is classifying the issue as CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: clk: mediatek: mt7622-apmixedsys: Fix an error handling path in clk_mt8135_apmixed_probe() 'clk_data' is allocated with mtk_devm_alloc_clk_data(). So calling mtk_free_clk_data() explicitly in the remove function would lead to a double-free. Remove the redundant call.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2024-27433 since 02/25/2024. Technical details are known, but there is no available exploit.
