Linux · Linux Kernel · CVE-2019-12381
**Name of the Vulnerable Software and Affected Versions**
Linux kernel versions through 5.1.5
**Description**
An issue was discovered in the ip ra control function in the net/ipv4/ip sockglue.c component of the Linux kernel. This issue is related to errors in pointer dereferencing, which might allow an attacker to cause a denial of service, resulting in a system crash due to a NULL pointer dereference. However, it is noted that this issue is disputed because the affected variable is never used if it is NULL.
**Recommendations**
For Linux kernel versions through 5.1.5, update to a version later than 5.1.5 to resolve the issue.
At the moment, there is no information about additional mitigation measures for this specific issue.
