CVE-2026-23410
HighSummary
W jądrze Linuxa zidentyfikowano podatność związaną z warunkiem wyścigu, która prowadzi do sytuacji use-after-free. Problem dotyczy braku liczenia referencji dla inodów rawdata, co umożliwia atakującemu otwieranie plików rawdata w niebezpieczny sposób.
Risk Assessment
Podatność ta może prowadzić do nieautoryzowanego dostępu do pamięci, co stwarza ryzyko dla integralności systemu oraz danych. Atakujący może wykorzystać tę lukę do przeprowadzenia dalszych ataków na system.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, w której ta podatność została naprawiona. Należy również monitorować systemy pod kątem podejrzanej aktywności związanej z plikami rawdata.
