GHSA-PP84-CM99-PP2Q
Vulnerability from github – Published: 2024-05-01 06:31 – Updated: 2025-09-18 15:30In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3-am62: fix module unload/reload behavior
As runtime PM is enabled, the module can be runtime suspended when .remove() is called.
Do a pm_runtime_get_sync() to make sure module is active before doing any register operations.
Doing a pm_runtime_put_sync() should disable the refclk so no need to disable it again.
Fixes the below warning at module removel.
[ 39.705310] ------------[ cut here ]------------ [ 39.710004] clk:162:3 already disabled [ 39.713941] WARNING: CPU: 0 PID: 921 at drivers/clk/clk.c:1090 clk_core_disable+0xb0/0xb8
We called of_platform_populate() in .probe() so call the cleanup function of_platform_depopulate() in .remove(). Get rid of the now unnnecessary dwc3_ti_remove_core(). Without this, module re-load doesn't work properly.
