In the Linux kernel, the following vulnerability has been resolved:

tls: fix race between async notify and socket close

The submitting thread (one which called recvmsg/sendmsg)

may exit as soon as the async crypto handler calls complete()

so any code past that point risks touching already freed data.

Try to avoid the locking and extra flags altogether.

Have the main thread hold an extra reference, this way

we can depend solely on the atomic ref counter for

synchronization.

Don't futz with reiniting the completion, either, we are now

tightly controlling when completion fires.

建议您更新当前系统或软件至最新版，完成漏洞的修复。
