UARPUpdaterServiceUSBPD process consuming huge amounts of memory

Periodically, the UARPUpdaterServiceUSBPD process will start consuming huge amounts of memory on my system. The amount of memory grows over time, so this appears to be a memory leak. The fans on my MacBook spin up, and the system in general slows down. I have to either forcefully stop the process or restart my MacBook to get the system to get back to normal.

Searching around, this appears to be a widespread problem. See:

Some of my system info:

1.1 GHz Quad-Core Intel Core i5
16 GB 3733 MHz LPDDR4X
macOS Sonoma Version 14.4.1 (23E224)
No external devices attached, although I do have nearby bluetooth devices. There does not seem to be a pattern of if the bluetooth devices are connected or not.

Is Apple aware of this problem? Are there any fixes coming soon?

MacBook Air 13″, macOS 14.4

Further results: After several days with the charger connected on the right front USBC instead of the right rear while running Sonoma 14.4.1, this process would occasionally show up in Activity Monitor, showing about 4MB of RAM usage, then vanish.

After updating to Sonoma 14.5, the behavior using the right front port is the same: shows up initially then goes away without ever growing huge. On the right rear port after 5 hours it is still sitting there at 4.3MB. I'll leave it there overnight to see whether something fires while idle or after a long interval to trigger it.

I conclude that Apple fixed the leak in 14.5, but I don't understand why the two ports yield different results.

This is all on an Intel-based 2019 16" MacBookPro.
