CVE-2026-21537
HighSummary
Nieprawidłowa kontrola generowania kodu ('iniekcja kodu') w Microsoft Defender dla systemu Linux umożliwia nieautoryzowanemu atakującemu wykonanie kodu w sąsiedniej sieci.
Risk Assessment
Atakujący może wykorzystać tę podatność do zdalnego wykonania kodu, co może prowadzić do przejęcia kontroli nad systemem lub kradzieży danych.
Recommendation
Zaleca się aktualizację Microsoft Defender do najnowszej wersji oraz monitorowanie ruchu sieciowego w celu wykrycia potencjalnych prób ataków.
