CVE-2026-32280 — Unexpected work during chain building in crypto/x509

Affected: Go standard library crypto/x509, Red Hat Cryostat 4 on RHEL 9, Red Hat HawtIO HawtIO 4.4.0, Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9, Red Hat Ansible Automation Platform 2.6 for RHEL 10, Red Hat Ansible Automation Platform 2.6 for RHEL 9, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 10.0 Extended Update Support, Red Hat Enterprise Linux 7 Extended Lifecycle Support and 132 more

During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls.

GHSA-j88v-2chj-qfwx — pgx: SQL Injection via placeholder confusion with dollar quoted string literals

Affected: Go: github.com/jackc/pgx/v5, Go: github.com/jackc/pgx/v4, Go: github.com/jackc/pgx

### Impact

SQL Injection can occur when:

1. The non-default simple protocol is used. 2. A dollar quoted string literal is used in the SQL query. 3. That string literal contains text that would be would be interpreted as a placeholder outside of a string literal. 4. The value of that placeholder is controllable by the attacker.

e.g.

```go attackValue := `$tag$; drop table canary; --` _, err = tx.Exec(ctx, `select $tag$ $1 $tag$, $1`, pgx.QueryExecModeSimpleProtocol, attackValue) ```

This is unlikely to occur outside of a contrived scenario.

### Patches

The problem is resolved in v5.9.2.

### Workarounds

Do not use the simple protocol to execute queries matching all the above conditions.
