Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： crypto: tegra - 修复 tegra_gcm_do_one_req() 中 rctx->cryptlen 的计算 在 中，以与 中相同的方式计算 。当前的计算公式可能导致崩溃：如果调用者未调用 ， 将保持为 0。此时，使用不正确的 执行解密操作，会导致对 缓冲区发生越界写入。 作为后续的清理工作，删除了 中的 字段，因为该字段似乎完全未被使用。同时，分别简化了 和 函数。

Vulnerability Title
crypto: tegra - fix rctx->cryptlen calculation in tegra_gcm_do_one_req()
Source: CVE Program / CVE List V5
Vulnerability 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.
