| Subject: CVE-2024-26963: usb: dwc3-am62: fix module unload/reload behavior |
| |
| Description |
| =========== |
| |
| In 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26963 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
