Opening

Today, three stories about what a tool can find and what people still have to verify. Linux security fixes, a planet hiding in Webb’s data, and a mobile spying campaign.

OpenAI’s Linux kernel audit

OpenAI says its research pipeline produced working exploits for nine hundred and forty-eight distinct Linux kernel flaws. That was a controlled audit, with code already running under an ordinary user account. The exploits showed how a local user could gain administrator privileges under the test conditions. The team also generated candidate patches. Those patches still need review by people familiar with the affected code. A proposed fix can correct the test case and still cause problems in other parts of the kernel. A fix also has to reach the branch a distribution ships. Then the machine needs to boot into a kernel that contains it. For an administrator, the useful check is the vendor advisory for the system you operate. Compare the fixed package with the kernel that is actually running. The research total cannot answer that for you.

Webb recovers 51 Eridani b

A giant planet was hiding in an observation the Webb telescope made in twenty twenty-three. Astronomers already knew the planet, fifty-one Eridani b. Earlier processing missed it in one infrared band. A research team modeled how the telescope spread light from the host star across the image. With a better model of that glare, the planet’s signal came through at four point three microns. The team reports about four times better detection sensitivity at the planet’s position in that observation. That wavelength matters because it can help researchers study the planet’s atmosphere. Working out the atmospheric composition will take further analysis. The sensitivity gain applies to this observation. It is a reason to look again at old telescope data, where signals may have survived an earlier analysis.

Mobile spying reused patched flaws

Security researchers at Sekoia recovered three exploit chains aimed at iPhones and Android devices. The campaign reached visitors through compromised sites, imitation sites and a tampered website analytics script. The code checked which browser and device it was dealing with. It then selected a matching attack. The underlying flaws already had fixes. Older versions still gave the attackers a route in. The tools could steal browser cookies and, in some cases, other information stored on the phone. The researchers give no verified count of how many phones the campaign compromised. On iPhone, verify the system update that is installed. On Android, check the device security patch and the Chrome update separately. If you are investigating a suspected compromise, keep that response separate from patching. A patch closes a route in. It cannot recover data already taken.
