CVE-2024-0564
LowSummary
W jądrze Linuxa znaleziono lukę w mechanizmie deduplikacji pamięci. Maksymalne udostępnianie stron w Kernel Samepage Merging (KSM), wprowadzone w wersji jądra 4.4.0-96.119, może stworzyć kanał boczny.
Risk Assessment
Atakujący, który dzieli ten sam host z ofiarą, może wykorzystać tę lukę do uzyskania dostępu do wrażliwych informacji. Istnieje ryzyko naruszenia poufności danych w środowiskach współdzielonych.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę lukę. Należy również rozważyć zmianę domyślnych ustawień KSM w celu ograniczenia ryzyka.

mJobTime through build 15.7.3.32 contains an unauthenticated SQL execution vulnerability in the Login.aspx admin panel handlers, where the runQueryButton postback and exportSqlQuery_Server PageMethod execute caller-supplied SQL against the backing Sybase SQL Anywhere database using DBA/sysadmin privileges with no server-side authentication enforced beyond a client-side sessionStorage flag. Attackers can submit arbitrary SQL through these exposed endpoints to invoke xp_cmdshell and xp_read_file, achieving pre-authentication remote code execution as LocalSystem via a single HTTP request.

Integrics Enswitch 3.13 through 4.4 contains an authentication bypass vulnerability in /api/json/user/password/update/ that allows unauthenticated attackers to change account passwords by omitting the reset parameter. Attackers can target accounts with no pending reset, whose empty reset_key matches the defaulted empty value, to take over administrator accounts after enumerating valid usernames.

- CVE-2026-103663Critical
Ollama is vulnerable to path traversal in the `/api/pull` endpoint due to insufficient validation of layer digests by the `digestToPath` function. An unauthenticated remote attacker can specify a path traversal sequence as a layer digest, causing a malicious binary to be written outside the model store. Critically if the server process has write access to `/usr/lib/ollama` (the default in most Ollama Docker images), an attacker can write the malicious file to that directory. On the next server restart, the file is loaded and executed, resulting in remote code execution as root. This issue was fixed in version 0.35.0.

A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharin
