CVE-2026-25068
MediumSummary
Wersje alsa-lib od 1.2.2 do 1.2.15.2 zawierają podatność na przepełnienie bufora w sterowniku dekodera mixer control. Funkcja tplg_decode_control_mixer1() odczytuje pole num_channels z niezweryfikowanych danych .tplg i używa go jako granicy pętli bez walidacji.
Risk Assessment
Podatność ta może prowadzić do wykonania złośliwego kodu w kontekście aplikacji korzystającej z alsa-lib, co stwarza poważne zagrożenie dla bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację alsa-lib do wersji zawierającej poprawki po commit 5f7fe33, aby zlikwidować ryzyko związane z tą podatnością.
