CVE-2026-43044
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z obsługą długich kluczy HMAC w module CAAM. Problem polegał na niewłaściwym zaokrąglaniu pamięci przy kopiowaniu kluczy dłuższych niż rozmiar bloku, co mogło prowadzić do uszkodzenia pamięci.
Risk Assessment
Organizacje mogą być narażone na ryzyko uszkodzenia danych lub nieautorywanych operacji, jeśli nie zastosują odpowiednich poprawek. Wykorzystanie tej podatności może prowadzić do poważnych problemów z bezpieczeństwem systemów opartych na jądrze Linux.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, która zawiera poprawki dla tej podatności. Należy również monitorować systemy pod kątem potencjalnych nieautoryzowanych działań.
