Samsung vulnerabilities

Improper authorization in KnoxGuardManager prior to SMR Feb-2026 Release 1 allows local attackers to bypass the persistence configuration of the application.

Improper access control in Emergency Sharing prior to SMR Feb-2026 Release 1 allows local attackers to interrupt its functioning.

An issue was discovered in the Wi-Fi driver in Samsung Mobile Processor and Wearable Processor Exynos 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930 and W1000. There is unbounded memory allocation via a large buffer in a /proc/driver/unifi0/confg_tspec write operation, leading to kernel memory exhaustion.
