CVE-2024-50012
MediumCVSS 5.5Summary
W jądrze Linuxa rozwiązano podatność związaną z niewłaściwym zarządzaniem licznikami referencji na węźle CPU. W funkcji parse_perf_domain, w przypadku błędu podczas wywołania of_parse_phandle_with_args, odniesienie do węzła urządzenia CPU nie jest prawidłowo dekrementowane.
Risk Assessment
Niewłaściwe zarządzanie licznikami referencji może prowadzić do wycieków pamięci lub nieprzewidzianych zachowań systemu, co może wpłynąć na stabilność i bezpieczeństwo systemu operacyjnego.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe zarządzanie zasobami systemowymi.

Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: cpufreq: Avoid a bad reference count on CPU node In the parse_perf_domain function, if the call to of_parse_phandle_with_args returns an error, then the reference to the CPU device node that was acquired at the start of the function would not be properly decremented. Address this by declaring the variable with the __free(device_node) cleanup attribute.
