CVE-2019-12381

MEDIUM

Linux Kernel < 5.1.5 - Denial of Service via NULL Pointer Dereference in ip_ra_control

Title source: llm
STIX 2.1

Description

An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: this is disputed because new_ra is never used if it is NULL
