CWE-476  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:6 python-perf.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-perf package and not the python-perf package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel through 4.2.3 does not ensure that certain slot numbers are valid, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call.
