CVE-2026-43400
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z brakiem górnej granicy sprawdzania wartości wejściowych w funkcji amdgpu_userq_signal_ioctl. Duże wartości wejściowe mogą prowadzić do wyczerpania pamięci (OOM) i mogą być wykorzystane w ataku.
Risk Assessment
Organizacje mogą być narażone na ataki, które prowadzą do wyczerpania pamięci, co może skutkować awarią systemu lub utratą dostępności usług.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby załatać tę podatność oraz monitorowanie wartości wejściowych w funkcji amdgpu_userq_signal_ioctl.

Joomla Extension - balbooa.com - Unauthenticated RCE via field shortcode injection in Balbooa Forms < 2.4.3.4 - Balbooa Forms supports administrator-defined PHP code which runs after a public form submission. The feature also supports form-field shortcodes inside that PHP. Before calling `eval()`, the component replaces each shortcode with the raw value submitted by the visitor, leading to an RCE vector. A public form must use the product's optional PHP-after-submission action and interpolate an attacker-controlled field shortcode inside a double-quoted PHP string to be vulnerable.

Fumasoft Fumeng Cloud contains a SQL injection vulnerability in the AjaxMethod.ashx endpoint that allows unauthenticated remote attackers to inject arbitrary SQL through the Name parameter of the getEmpByname action without any authentication. Attackers can exploit UNION-based SQL injection techniques against the Microsoft SQL Server backend to extract, disclose, and modify database contents, with potential for further compromise of the underlying server. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.
