AI-suggested
A fix is available that clears the forceRM bit when issuing the EndTransfer command in the USB DWC3 driver. Users should update to patched Linux kernel versions that include this correction. No additional mitigation steps are indicated or required beyond applying the official fix.
Description
A vulnerability in the Linux kernel's USB DWC3 driver related to the handling of the forceRM bit in the DEPCMD register during EndTransfer has been resolved. The issue caused aborted transfers to remain active, leading to SMMU faults due to buffer unmapped accesses. The fix involves clearing the forceRM bit when issuing EndTransfer, aligning with updated programming guide recommendations.
