CVE-2022-49396 Details
Description
In the Linux kernel, the following vulnerability has been resolved: phy: qcom-qmp: fix reset-controller leak on probe errors Make sure to release the lane reset controller in case of a late probe error (e.g. probe deferral). Note that due to the reset controller being defined in devicetree in "lane" child nodes, devm_reset_control_get_exclusive() cannot be used directly.
A vulnerability in the Linux kernel's QCOM QMP PHY implementation has been addressed. The issue involved a leak of the lane reset controller during probe errors, particularly in cases of probe deferral. The vulnerability arose because the reset controller is defined in the device tree under 'lane' child nodes, preventing the direct use of the 'devm_reset_control_get_exclusive()' function.
