Exynos 2500 Firmware

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).
