CVE-2026-43445
MediumSummary
W jądrze Linuxa naprawiono podatność związaną z wyciekiem w procesie czyszczenia błędów DMA w sterownikach e1000/e1000e. Problem występował podczas mapowania buforów TX, gdzie nieodpowiednio odmapowywano już zmapowane bufory w przypadku wystąpienia błędu.
Risk Assessment
Organizacje mogą być narażone na problemy z wydajnością i stabilnością systemu, jeśli nie zostaną podjęte odpowiednie kroki w celu aktualizacji jądra. W przypadku wystąpienia błędów w mapowaniu buforów, może to prowadzić do nieprzewidzianych zachowań systemu.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność oraz zapewnić prawidłowe zarządzanie buforami w sterownikach e1000/e1000e.

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.
