AEAD加密操作中存在空指针解引用漏洞
漏洞描述信息
在Linux内核中,已修复以下漏洞:
KEYS: trusted: dcp: 修复AEAD加密操作中的空指针解引用问题
在密封或解封密钥Blob时,当前我们不会等待AEAD加密操作完成,而是在提交请求后直接返回。如果系统负载较大,我们可能会在加密操作完成前就退出,此时读取/写入的缓冲区已经从栈中移除。这将导致在创建Blob时DCP驱动中出现空指针解引用错误。
通过在恢复密封和解封调用之前等待AEAD加密操作完成来修复此问题。

KEYS: trusted: dcp: fix NULL dereference in AEAD crypto operation
漏洞描述信息
In the Linux kernel, the following vulnerability has been resolved:
KEYS: trusted: dcp: fix NULL dereference in AEAD crypto operation
When sealing or unsealing a key blob we currently do not wait for
the AEAD cipher operation to finish and simply return after submitting
the request. If there is some load on the system we can exit before
the cipher operation is done and the buffer we read from/write to
is already removed from the stack. This will e.g. result in NULL
pointer dereference errors in the DCP driver during blob creation.
Fix this by waiting for the AEAD cipher operation to finish before
resuming the seal and unseal calls.
