alt Hacker NewsAs mentioned in the article, every bug is potentially a security problem to someone.
If you know that something is a security issue to your organization, you definitely don't want to paint a target on your back by reporting the bug publicly with an email address <your_name>@<your_org>.com. In the end, it is really actually quite rare (given the size of the code base and the popularity of linux) that a bug has a very wide security impact.
The vast majority of security issues don't affect organizations that are serious about security (yes really, SELinux eliminates or seriously reduces the impact of the vast majority of security bugs).
The problem with that argument is that the reports don’t necessarily come from the organization for whom it’s an issue. Security researchers unaffiliated not impacted by any such issue still report it this way (eg Project Zero reporting issues that don’t impact Google at all).
Also Android uses SELinux and still has lots of kernel exploits. Believing SELinux solves the vast majority of security issues is fallacious, especially since it’s primarily about securing userspace, not the kernel itself .
