CVE-2024-39492 Details
Description
In the Linux kernel, the following vulnerability has been resolved: mailbox: mtk-cmdq: Fix pm_runtime_get_sync() warning in mbox shutdown The return value of pm_runtime_get_sync() in cmdq_mbox_shutdown() will return 1 when pm runtime state is active, and we don't want to get the warning message in this case. So we change the return value < 0 for WARN_ON().
A vulnerability related to improper handling of runtime power management states has been identified in the Linux kernel's mailbox MTK CMDQ driver. The issue arises in the 'cmdq_mbox_shutdown()' function, where the return value of 'pm_runtime_get_sync()' incorrectly triggers a warning when the power management state is active. This vulnerability affects the Linux kernel stable tree.
Users can apply the available patch in the Linux kernel stable tree to address this vulnerability.
