Public bug reported:
Ubuntu 25.10, currently running 6.17.0 compiled from source on Dell
M6700.
Sending keyboard data at keyboard repetition rate (i.e. holding down a key)
into a USB CDC via minicom.
A failure in the USB CDC device comms somehow causes minicom to crash due to
internal stack smashing.
ProblemType: Crash
ApportVersion: 2.33.1-0ubuntu3
Architecture: amd64
AssertionMessage: *** stack smashing detected ***: terminated
