Error in 3GPP specification implementation in Exynos baseband prior to SMR Apr-2023 Release 1 allows incorrect handling of unencrypted message.

An issue was discovered in Samsung Mobile Processor, Wearable Processor, and Modem Exynos 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 9110, W920, W930, W1000, Modem 5123, Modem 5300, and Modem 5400. A programming mistake for buffer copy leads to out-of-bounds writes via malformed ROHC packets.

Improper verification of intent by SamsungExceptionalBroadcastReceiver in S Assistant prior to version 9.3.2 allows local attackers to modify itinerary information.

Improper verification of intent by SystemExceptionalBroadcastReceiver in S Assistant prior to version 9.3.2 allows local attackers to modify itinerary information.

Improper access control vulnerability in SemClipboard prior to SMR Apr-2023 Release 1 allows attackers to read arbitrary files with system permission.

Improper input validation with Exynos Fastboot USB Interface prior to SMR Apr-2023 Release 1 allows a physical attacker to execute arbitrary code in bootloader.

Improper input validation with Exynos Fastboot USB Interface prior to SMR Apr-2023 Release 1 allows a physical attacker to execute arbitrary code in bootloader.

Improper verification of intent by ExternalBroadcastReceiver in S Assistant prior to version 9.3.2 allows local attackers to modify itinerary information.

Improper access control in ImsService prior to SMR Sep-2025 Release 1 allows local attackers to use the privileged APIs.

An issue was discovered in Samsung Mobile Processor and Wearable Processor Exynos 850, Exynos 1080, Exynos 2100, Exynos 1280, Exynos 1380, Exynos 1330, Exynos W920, Exynos W930. The mobile processor lacks proper reference count checking, which can result in a UAF (Use-After-Free) vulnerability.

Improper access control in accessing system device node prior to SMR Aug-2025 Release 1 allows local attackers to access device identifier.

An issue was discovered in Samsung Mobile Processor, Wearable Processor, and Modem Exynos 9820, 9825, 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 9110, W920, W930, W1000, Modem 5123, Modem 5300. The baseband software does not properly check the length specified by the CC (Call Control). This can lead to an Out-of-Bounds write.

A vulnerability was discovered in Samsung Mobile Processor, Wearable Processor, and Modems with versions Exynos 9820, Exynos 9825, Exynos 980, Exynos 990, Exynos 850, Exynos 1080, Exynos 2100, Exynos 2200, Exynos 1280, Exynos 1380, Exynos 1330, Exynos 9110, Exynos W920, Exynos W930, Exynos Modem 5123, and Exynos Modem 5300 that involves incorrect authorization of LTE NAS messages and leads to downgrading to lower network generations and repeated DDOS.

The Remote Controls feature on Samsung mobile devices does not validate the source of lock-code data received over a network, which makes it easier for remote attackers to cause a denial of service (screen locking with an arbitrary code) by triggering unexpected Find My Mobile network traffic.

An issue was discovered in Samsung Exynos Mobile Processor and Wearable Processor (Exynos 980, Exynos 850, Exynos 2100, and Exynos W920). Improper handling of length parameter inconsistency can cause incorrect packet filtering.
