Debian Linux Kernel Multiple Vulnerabilities

Multiple vulnerabilities were identified in Debian Linux Kernel. A remote attacker could exploit some of these vulnerabilities to trigger denial of service condition, elevation of privilege, sensitive information disclosure and remote code execution on the targeted system.

Note:

Proof-of-concept code is publicly available for CVE-2026-46242. An elevation of privilege vulnerability ("Bad Epoll") is found in the Linux kernel. This vulnerability could allow local attackers reuse freed memory with attacker-controlled data, potentially leading to root privileges. Hence, the risk level is rated as Medium Risk.

Proof-of-concept code is publicly available for CVE-2026-43499. A local attacker could potentially exploit this to gain elevated privileges or execute unauthorized code. Hence, the risk level remains unchanged as Medium Risk.

Recent research indicates that CVE-2026-43499 can chain with Firefox flaws (CVE-2026-10702) to potentially allow remote attackers to gain full device control.
