Detailsinfo

A vulnerability was found in Linux Kernel up to 5.15.152/6.1.82/6.6.22/6.7.10/6.8.1. It has been rated as problematic. This issue affects the function devm_kfree of the component hi3559a. The manipulation with an unknown input leads to a iteration vulnerability. Using CWE to declare the problem leads to CWE-834. The product performs an iteration or loop without sufficiently limiting the number of times that the loop is executed. Impacted is availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: clk: hisilicon: hi3559a: Fix an erroneous devm_kfree() 'p_clk' is an array allocated just before the for loop for all clk that need to be registered. It is incremented at each loop iteration. If a clk_register() call fails, 'p_clk' may point to something different from what should be freed. The best we can do, is to avoid this wrong release of memory.

It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2024-27039 since 02/19/2024. Technical details of the vulnerability are known, but there is no available exploit.
