CVE-2025-71231
HighSummary
W jądrze systemu Linux zidentyfikowano podatność związaną z nieprawidłowym indeksem w funkcji find_empty_iaa_compression_mode. Zmienna lokalna 'i' jest inicjowana wartością -EINVAL, ale pętla for natychmiast ją nadpisuje, co prowadzi do zwrócenia nieprawidłowego indeksu IAA_COMP_MODES_MAX, jeśli nie znaleziono pustego trybu kompresji.
Risk Assessment
Podatność ta może prowadzić do nieprawidłowego dostępu do tablicy, co może skutkować awarią systemu lub nieprzewidzianym zachowaniem aplikacji korzystających z tego mechanizmu. Może to wpłynąć na stabilność i bezpieczeństwo systemu.
Recommendation
Zaleca się aktualizację jądra systemu Linux do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe działanie funkcji związanych z kompresją.

Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode The local variable 'i' is initialized with -EINVAL, but the for loop immediately overwrites it and -EINVAL is never returned. If no empty compression mode can be found, the function would return the out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid array access in add_iaa_compression_mode(). Fix both issues by returning either a valid index or -EINVAL.
