CVE-2026-80882

False crypto success via retained zero status

Published Sep 4, 2026 · Updated Sep 4, 2026

Error handling in the Linux Tegra CCM driver allows local users to receive false success from requests after input-buffer allocation fails. In tegra_ccm_do_one_req, a successful initializer leaves ret at zero, and a failed input DMA allocation jumps to finalization without replacing it with ENOMEM. The condition requires the Tegra Security Engine CCM path and a failed DMA allocation; the request can then complete as if cryptographic work succeeded.
