Exynos 850 Firmware
Monthly
The MFC (Multi Format Codec) encoder driver in Samsung Exynos mobile and wearable processors contains a double-free vulnerability triggered by improper cleanup of dma_buf references during error handling paths. The flaw spans seventeen Exynos SoC variants - Exynos 850 through 2600 mobile series and W920/W930/W1000 wearable chips - present in Samsung Galaxy smartphones and Galaxy Watch devices, and can lead to kernel heap corruption with potential local privilege escalation to arbitrary kernel-mode code execution. No active exploitation has been confirmed (not listed in CISA KEV) and no public proof-of-concept is identified in the available input data.
NULL pointer dereference in the 5G NR baseband of Samsung Exynos processors and modems causes a denial-of-service condition when a malformed RRC Reconfiguration message is received from the network. Sixteen Exynos chip variants are affected, spanning Samsung flagship, mid-range, and wearable devices - including Exynos 850, 1080, 2100, 2200, 2400, W920, W930, W1000, Modem 5410, and others. An attacker capable of injecting or spoofing RRC layer signaling (e.g., via a rogue base station) can trigger a crash in the L2/RRC processing stack, disrupting cellular connectivity. No public exploit code or active exploitation has been identified at time of analysis.
Denial of service in Samsung Exynos USIM firmware across mobile, wearable, and modem processors allows unauthenticated remote attackers to crash affected devices via maliciously crafted SIM card proactive commands. The vulnerability affects over 20 Exynos chipset families (980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 2500, 9110, W920, W930, W1000, Modem 5123, 5300, 5400) due to improper handling of USIM proactive commands, classified as CWE-400 (Uncontrolled Resource Consumption). EPSS exploitation probability is low (0.02%, 5th percentile), no public exploit identified at time of analysis, and not currently listed in CISA KEV. Despite the high CVSS base score of 7.5, the practical exploitation requires attacker control over cellular network infrastructure or compromised SIM cards, significantly limiting real-world attack surface.
System crash in Samsung Exynos processors (980/990/850/1080/2100/1280/2200/1330/1380/1480/2400/1580/2500/9110, Wearable W920/W930/W1000, Modems 5123/5300/5400) allows unauthenticated remote attackers to trigger denial-of-service via malformed RRCReconfiguration message exploiting improper memory initialization in the Radio Resource Control (RRC) layer. No public exploit identified at time of analysis. EPSS score of 0.02% (5th percentile) indicates very low probability of imminent exploitation despite network-reachable attack surface and low complexity (CVSS 7.5, AV:N/AC:L/PR:N).

The MFC (Multi Format Codec) encoder driver in Samsung Exynos mobile and wearable processors contains a double-free vulnerability triggered by improper cleanup of dma_buf references during error handling paths. The flaw spans seventeen Exynos SoC variants - Exynos 850 through 2600 mobile series and W920/W930/W1000 wearable chips - present in Samsung Galaxy smartphones and Galaxy Watch devices, and can lead to kernel heap corruption with potential local privilege escalation to arbitrary kernel-mode code execution. No active exploitation has been confirmed (not listed in CISA KEV) and no public proof-of-concept is identified in the available input data.
NULL pointer dereference in the 5G NR baseband of Samsung Exynos processors and modems causes a denial-of-service condition when a malformed RRC Reconfiguration message is received from the network. Sixteen Exynos chip variants are affected, spanning Samsung flagship, mid-range, and wearable devices - including Exynos 850, 1080, 2100, 2200, 2400, W920, W930, W1000, Modem 5410, and others. An attacker capable of injecting or spoofing RRC layer signaling (e.g., via a rogue base station) can trigger a crash in the L2/RRC processing stack, disrupting cellular connectivity. No public exploit code or active exploitation has been identified at time of analysis.
Denial of service in Samsung Exynos USIM firmware across mobile, wearable, and modem processors allows unauthenticated remote attackers to crash affected devices via maliciously crafted SIM card proactive commands. The vulnerability affects over 20 Exynos chipset families (980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 2500, 9110, W920, W930, W1000, Modem 5123, 5300, 5400) due to improper handling of USIM proactive commands, classified as CWE-400 (Uncontrolled Resource Consumption). EPSS exploitation probability is low (0.02%, 5th percentile), no public exploit identified at time of analysis, and not currently listed in CISA KEV. Despite the high CVSS base score of 7.5, the practical exploitation requires attacker control over cellular network infrastructure or compromised SIM cards, significantly limiting real-world attack surface.
System crash in Samsung Exynos processors (980/990/850/1080/2100/1280/2200/1330/1380/1480/2400/1580/2500/9110, Wearable W920/W930/W1000, Modems 5123/5300/5400) allows unauthenticated remote attackers to trigger denial-of-service via malformed RRCReconfiguration message exploiting improper memory initialization in the Radio Resource Control (RRC) layer. No public exploit identified at time of analysis. EPSS score of 0.02% (5th percentile) indicates very low probability of imminent exploitation despite network-reachable attack surface and low complexity (CVSS 7.5, AV:N/AC:L/PR:N).
