NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt_debug package and not the kernel-rt_debug package as distributed by SLES.

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.
