CVE-2025-36917Network attack vector

Remote service interruption via incorrect buffer bounds

Published Dec 11, 2025 · Updated Dec 11, 2025

Buffer overflow in the Exynos-SLSI kernel component in Google Android allows remote authenticated users to interrupt device service. The SwDcpItg function in up_L2commonPdcpSecurity.cpp applies an incorrect bounds check during a buffer copy, allowing the copy to exceed its destination. Low privileges are required, no user interaction is needed, and the published impact is limited to loss of availability rather than data disclosure or modification.
