In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
crypto: tegra – fix rctx->cryptlen calculation in tegra_gcm_do_one_req()<\/p>\n
Perform rctx->cryptlen calculation in tegra_gcm_do_one_req() the same way
\nit is done in tegra_ccm_crypt_init(). The current formulae may lead to a
\ncrash if a caller does not call tegra_gcm_setauthsize() and so ctx->authsize
\nremains zero. Then a decrypt operation with incorrect rctx->cryptlen will
\nlead to a write beyound rctx->dst_sg buffer.<\/p>\n
As a follow-up cleanup delete struct tegra_aead_ctx->authsize field since
\nit appears to be completely unused. Also simplify tegra_ccm_setauthsize()
\nand tegra_gcm_setauthsize() functions respectively.<\/p>\n","protected":false},"excerpt":{"rendered":"
