Overview

CVE-2026-80522 is a high-severity vulnerability. It was published on August 26, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
