UID2-7376: suppress CVE-2026-2100 (p11-kit) — not exploitable#663
Merged
Conversation
CVE-2026-2100 is a NULL pointer dereference in p11-kit (Alpine base image) triggered via C_DeriveKey. Our services are pure Java: the JVM uses JSSE for TLS and the Java cacerts keystore for trust, and never loads the native p11-kit PKCS#11 module loader or calls C_DeriveKey, so the vulnerable code path is not reachable. Following the established treatment for non-exploitable native base-image CVEs (cf. CVE-2026-45447 libcrypto3), this is suppressed in .trivyignore with a 'not reachable from the JVM' rationale and an expiry, rather than upgraded. A fix exists in Alpine v3.23 (>= 0.26.2-r0) but the pinned eclipse-temurin base image has not yet been rebuilt with it; the expiry resurfaces this for review once that lands.

Summary
Suppresses CVE-2026-2100 (HIGH) — a NULL pointer dereference in
p11-kit(Alpine base image) viaC_DeriveKey— in.trivyignore, with an expiry of 2026-09-01.Why suppress rather than upgrade
This service is pure Java. The JVM uses JSSE for TLS and the bundled Java
cacertskeystore for trust validation — it never loads the nativep11-kitPKCS#11 module loader and never callsC_DeriveKey, so the vulnerable code path is not reachable. The package is present only as a transitive dependency of the Alpine base image.This follows the team's established treatment for non-exploitable native base-image CVEs (cf.
CVE-2026-45447libcrypto3, already suppressed here with the same 'JVM uses JSSE, not the native lib' rationale). A fix exists in Alpine v3.23 (>= 0.26.2-r0) but the pinnedeclipse-temurinbase image has not yet been rebuilt with it; the expiry resurfaces this for review once that lands. Suppression is self-cleaning, whereas a manualapk --upgradeline would become silent dead weight once the base image catches up.Jira: UID2-7376
