JSON

A flaw was found in the Netlink device interface implementation in the Linux kernel that improperly handled certain error conditions, leading to a use-after-free issue with some network device drivers. A local attacker with admin access to the network device could use this to cause a denial of service (system crash) or execute arbitrary code.

Mitigation

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
