CVE-2026-31438
MediumSummary
W jądrze systemu Linux naprawiono podatność związaną z błędem w funkcji netfs_limit_iter() dla iteratorów ITER_KVEC. Problem występuje, gdy proces ulega awarii, a jądro zapisuje zrzut pamięci na systemie plików 9P.
Risk Assessment
Podatność ta może prowadzić do awarii systemu lub nieprzewidzianego zachowania, co może wpłynąć na stabilność i bezpieczeństwo aplikacji działających na serwerze.
Recommendation
Zaleca się aktualizację jądra systemu Linux do najnowszej wersji, aby usunąć tę podatność i zapewnić stabilność systemu.
