RU

Для пакета mesa 25.3.1 найдены CVE-кандидаты по данным NVD/CPE: CVE-2026-40393. Требуется triage security-team.

Проверить применимость CVE к сборке НАЙС.ОС, сопоставить с upstream/vendor advisory, определить статус affected/fixed/not_affected и при необходимости подготовить обновление пакета.

Рекомендуемое действие: needs_triage

Подсказка по целевой версии: -

Проверки: Проверить сборку RPM, обновление пакета, совместимость зависимостей, service/CLI smoke tests и регрессионные сценарии по классу пакета.

Риски: Автоматическое совпадение NVD/CPE не является финальным вердиктом по НАЙС.ОС.

EN

NVD/CPE candidate CVEs were found for mesa 25.3.1: CVE-2026-40393. Security-team triage is required.

Verify CVE applicability to the NiceOS build, compare with upstream/vendor advisories, set affected/fixed/not_affected status, and prepare a package update if required.

Recommended action: needs_triage

Target version hint: -

Tests: Run RPM build, package upgrade, dependency compatibility, service/CLI smoke tests, and package-class-specific regression tests.

Risks: An automatic NVD/CPE match is not the final NiceOS vulnerability verdict.

Descriptions

CVE-2026-40393

In Mesa before 25.3.6 and 26 before 26.0.1, out-of-bounds memory access can occur in WebGPU because the amount of to-be-allocated data depends on an untrusted party, and is then used for alloca.

Scanner integration / Интеграция со сканером

This issue was generated from niceos_cve_matches after the SPEC/Forgejo evidence pass.
After real creation, this script writes forgejo_issue_open rows into niceos_cve_evidence and marks the selected CVE rows as issue_open, so the next scanner/creator run does not duplicate the issue.

Maintainer checklist

Verify whether each CVE applies to the NiceOS build.
Compare NVD data with upstream/vendor advisory.
Set final NiceOS status: affected, fixed, not_affected, false_positive, deferred, or not_in_cloud_image.
If affected, decide update/backport strategy according to package policy class.
Run package-class-specific build, upgrade and regression tests.
Add/update niceos_cve_triage entry.
Create NICE-SA advisory if a security update is shipped.
