CVE-2026-4149
CriticalSummary
Podatność CVE-2026-4149 dotyczy urządzenia Sonos Era 300 i pozwala zdalnym atakującym na wykonanie dowolnego kodu. Problem wynika z niewłaściwego przetwarzania pola DataOffset w odpowiedziach SMB, co prowadzi do dostępu do pamięci poza przydzielonym buforem.
Risk Assessment
Wykorzystanie tej podatności może umożliwić atakującym przejęcie kontroli nad systemem operacyjnym, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji. Brak wymogu autoryzacji do przeprowadzenia ataku zwiększa ryzyko.
Recommendation
Zaleca się natychmiastowe zaktualizowanie oprogramowania Sonos Era 300 do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, monitorowanie i ograniczenie dostępu do urządzeń może pomóc w minimalizacji ryzyka.

A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
Sonos Era 300 SMB Response Out-Of-Bounds Access Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sonos Era 300. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the DataOffset field within SMB responses. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the kernel. Was ZDI-CAN-28345.
