Ubuntu Linux Kernel Multiple Vulnerabilities

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

Note:

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.
