CVE-2022-50247 Details
Description
In the Linux kernel, the following vulnerability has been resolved: usb: xhci-mtk: fix leakage of shared hcd when fail to set wakeup irq Can not set the @shared_hcd to NULL before decrease the usage count by usb_put_hcd(), this will cause the shared hcd not released.
A vulnerability in the Linux kernel's handling of the XHCI-MTK USB controller can lead to a memory leak of the shared host controller driver (HCD) when the wakeup interrupt cannot be set. This issue arises because the shared HCD cannot be set to NULL before decrementing the usage count, preventing the shared HCD from being properly released. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for upgrading the Linux kernel can be found in the official Linux documentation.
