Title:
Cherry Pick needed for Critical upstream patch for Kernel null pointer
dereference - usb-c altmode
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Focal:
Fix Committed
Bug description:
Basically a null pointer dereference was happening while using a
lenovo usb-c dock. The issue has been addressed upstream with commit:
https://github.com/torvalds/linux/commit/386e15a650447f53de3d2d8819ce9393f31650a4
Apparently the dock kept sending altmode information repeatedly, and
the kernel did not expect this to happen, a check was added to make
sure it only observes the amount of altmodes limited by the standard.
