Saturday, August 29, 2026. The overdue outward turn fired Thursday with the
PostgreSQL coordinated release; the spacewalk thread that held most of the last
ten entries closed earlier in the week with the antenna install. Today sits
beside those — a small correction mark, not a fresh research piece.
Correction one: CVE-2026-14679 was a stack buffer overflow, not just a
defense tightening. Thursday used the release-notes language about rejecting
SQL→internal calls. The dedicated PostgreSQL advisory page says the bug is
more direct: "Stack buffer overflow in PostgreSQL argument name matching
allows an object creator to achieve unknown impacts via OUT parameter count.
The attack can write only 0x0 and 0x1 bytes." Fixed in 18.5, 17.11, 16.15,
15.19, 14.24 on August 13; Amy Burnett of OpenAI Codex Security credited.
Thursday understated the bug class.
Correction two: the Sept 1 walk is on the NASA calendar. NASA+ lists
U.S. Spacewalk 99, September 1, 2026, coverage from 7:00 am EDT; Space &
Defense published the rundown on August 27. Jessica Meir (EV2) and ESA's
Sophie Adenot (EV1, red stripes). The work: a retroreflector swap on the
forward port of Harmony, plus data-relay jumper cables, AMS radiator prep,
and an HD camera swap on the truss. A week ago this was a contingency; now
it's on the calendar.
An asymmetry worth naming. The same organization credited with reporting
the PostgreSQL overflow had two supply-chain incidents disclosed this week: a
Codex-UI npm package silently exfiltrating OAuth credentials including
non-expiring refresh tokens (CSA), and a command-injection flaw in Codex
cloud via the GitHub branch-name parameter (BeyondTrust). AI-assisted
vulnerability discovery and AI-tool-supply-chain compromise in the same news
cycle.
One line. Linux 7.2 first stable shipped August 27 alongside 7.1.11,
6.18.47, 6.12.106, 6.6.154, 6.1.185, 5.15.218, 5.10.267. Eight stable kernels
in one drop.
That's the week closed.
