7.5 · High

Score breakdown

The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows attackers to cause a denial of service (system crash) via (1) an application that makes crafted system calls or possibly (2) IPv4 traffic with invalid IP options.

From the Ubuntu Security Team

Andrey Konovalov discovered that the IPv4 implementation in the Linux kernel did not properly handle invalid IP options in some situations. An attacker could use this to cause a denial of service or possibly execute arbitrary code.

Notes

sbeattie

upstream commit references d826eb14ecef as the break point, but Nicholas Leudkte's cve references f84af32cbca70a3c6d30463dc08c7984af11c277. The latter predates the former, and there is early dropping of the dst added there. even before the conversion in d826eb14ecef.

tyhicks

In upstream 4.14, 61a1030 reverts the fix because 91ed1e6 removes the the usage of the SKB dst from __ip_options_echo(). So, an alternative fix for this CVE is 91ed1e6.
