CVE-2024-27039

clk: hisilicon: hi3559a: Fix an erroneous devm_kfree()

Reserved:2024-02-19
Published:2024-05-01
Updated:2024-05-13

Description

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.
