Hello,

CVE-2019-12381 was fixed in the upstream linux kernel with the commit :-

• 425aa0e1d015 ("ip_sockglue: Fix missing-check bug in ip_ra_control()")

Could the patch be applied in order to v4.19.y, v4.14.y, v4.9.y and v4.4.y ?

Tests run:

• Chrome OS tryjobs

This doesn't fix a security vulnerability. There already was a check for allocation failure before dereferencing the returned pointer; it just wasn't in the most obvious place.

I've requested rejection of this CVE, and several other invalid reports from the same person.
