Výzkumníci ze společnosti ESET objevili 11 zapomenutých UEFI shim zavaděčů, které byly podepsány společností Microsoft, a které umožňují útočníkům obejít ochranu UEFI Secure Boot na většině zařízení. Microsoft je zneplatnil (přidal jejich hash do databáze dbx) v rámci aktualizace Patch Tuesday dne 9. června 2026. Uživatelé Linuxu mohou databází aktualizovat pomocí LVFS. Ověřit zneplatnění zavaděčů lze pomocí skriptu uefi-dbx-audit. Jedná se o CVE-2026-8863 a CVE-2026-10797.

Google s tím nesouhlasí.

Vývojáři Firefoxu proto také od září přecházejí na dvoutýdenní cyklus vydávání verzí. :-)
