Description Petr Matousek 2010-11-01 21:19:12 UTC
Description of problem:
The TIOCGICOUNT device ioctl in serial_core.c allows unprivileged users to read uninitialized stack memory, because the "reserved" member of the serial_icounter_struct struct declared on the stack is not altered or zeroed before being copied back to the user.
