CVE-2025-40286
MediumSummary
W jądrze Linuxa zidentyfikowano podatność, która prowadziła do możliwego wycieku pamięci w funkcji smb2_read(). Problem ten występował, gdy ksmbd_vfs_read() kończył się niepowodzeniem, co skutkowało brakiem zwolnienia pamięci.
Risk Assessment
Wyciek pamięci może prowadzić do zwiększonego zużycia zasobów systemowych, co w dłuższej perspektywie może wpłynąć na stabilność i wydajność systemu.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapobiec potencjalnym problemom z wydajnością.
