Description
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix multishot accept request leaks
Having REQ_F_POLLED set doesn't guarantee that the request is
executed as a multishot from the polling path. Fortunately for us, if
the code thinks it's multishot issue when it's not, it can only ask to
skip completion so leaking the request. Use issue_flags to mark
multipoll issues.
Affected configurations
• linux linux kernel (>= 5.19 < 6.0.10)
• linux linux kernel 6.1
