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. (NVD)
