CVE-2022-49861
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: mv_xor_v2: Fix a resource leak in mv_xor_v2_remove()
A clk_prepare_enable() call in the probe is not balanced by a corresponding clk_disable_unprepare() in the remove function.
Add the missing call.
