Subject: linux-stable-5.10-y CVE-2022-1508 of io_uring module

Message-ID: <20220505141159.3182874-1-guoxuenan@huawei.com> (raw)

Hi, Pavel & Jens
CVE-2022-1508[1] contains an patch[2] of io_uring. As Jones reported,
it is not enough only apply [2] to stable-5.10.
Io_uring is very valuable and active module of linux kernel.
I've tried to apply these two patches[3] [4] to my local 5.10 code, I
found my understanding of io_uring is not enough to resolve all conflicts.
Since 5.10 is an important stable branch of linux, we would appreciate
your help in soloving this problem.
