Note: Versions mentioned in the description apply only to the upstream linux-4.9 package and not the linux-4.9 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4.
