CVE-2026-80522: Linux

High severity, CVSS 7.8. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux: from 6.10, before 6.12.105 (fixed in 6.12.105); from 6.13, before 6.18.46 (fixed in 6.18.46); from 6.19, before 7.1.10 (fixed in 7.1.10)
