High [CVE-2026-80522] tegra - fix rctx->cryptlen calculation in tegra_gcm_do_one_req
CVE-2026-80522Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: crypto: tegra - fix rctx->cryptlen calculation in tegra_gcm_do_one_req() Perform rctx->cryptlen calculation in tegra_gcm_do_one_req() the same way it is done in tegra_ccm_crypt_init(). The current formulae may lead to a crash if a caller does not call tegra_gcm_setauthsize() and so ctx->authsize remains zero. Then a decrypt operation with incorrect rctx->cryptlen will lead to a write beyound rctx->dst_sg buffer. As a follow-up cleanup delete struct tegra_aead_ctx->authsize field since it appears to be completely unused. Also simplify tegra_ccm_setauthsize() and tegra_gcm_setauthsize() functions respectively. A flaw was found in the Linux kernel's Tegra cryptography module. An incorrect calculation in the…

- Mitigation guidance
- To prevent the `tegra_se_aes` crypto module from being loaded, blacklist it by creating a configuration file. Create `/etc/modprobe.d/blacklist-tegra.conf` with the content: ``` blacklist tegra_se_aes ``` Then, regenerate the initramfs and reboot the system for the changes to take effect: ```bash dracut -f -v $(uname -r) reboot ``` This action may affect system functionality if NVIDIA Tegra hardware and its cryptographic features are actively utilized.
