Subject: Re: [PATCH -next 0/2] fix nfsv4 bugs of opening with O_ACCMODE flag

Hi Xiaosong,

I sent the first email on 05.05.2022 to CVE-Request@...re.org to require them update the description with the following information. They replied that they will update the information within that day. However, they didn't updated the description and then I sent the second email and they didn't reply me.

Do you know any other ways to update the description.


"I need to update the CVE description as below:
After secondly opening a file with O_ACCMODE|O_DIRECT flags, nfs4_valid_open_stateid() will dereference NULL nfs4_state when lseek().
And its references should be updated as this:
https://github.com/torvalds/linux/commit/ab0fc21bc7105b54bafd85bd8b82742f9e68898a "

Best,
Tao
