CVE-2025-71290

Local denial of service via probe reference leak

Published May 6, 2026 · Updated May 6, 2026

Memory leak in the Linux Kernel ti_fpc202 driver 6.16 through 6.18.15 and 6.19 through 6.19.5 allows local users to exhaust memory. The fpc202_probe() child-node loop uses a non-scoped iterator that fails to release the current device-node reference when the loop exits early. Exploitation requires local low-privileged access and an affected kernel built with TI_FPC202 support on a system exposing the FPC202 I2C device-tree path; the bounded consequence is availability loss.
