Amazon Linux 2023 Security Advisory: ALAS2023-2026-1980
Advisory Released Date: 2026-07-20
Advisory Updated Date: 2026-07-20
Severity:
Important
Issue Overview:
A use-after-free / double-free in c-ares' query-completion handling. The
same flaw -- a query's callback being invoked while the query is still
linked in the channel's internal lookup structures -- is present at
multiple points in the resend/finish path (timeout handling, response
handling, and query dispatch). If the query, or for `ares_getaddrinfo()`
the owning `host_query`, is freed as a side effect of that callback, it
is then accessed and/or freed a second time. (CVE-2026-33630)
Affected Packages:
nodejs24
Issue Correction:
Run dnf update nodejs24 --releasever 2023.12.20260720 or dnf update --advisory ALAS2023-2026-1980 --releasever 2023.12.20260720 to update your system.
