Backport fix for “msg corruption in recvmsg”

[chrisvest]

Description

The ubuntu-latest images recently updated from 24.04.03 to 24.04.4, which now has kernel version 6.17.0-1008-azure.

This update brought with it a Linux kernel version that introduces the bug described in axboe/liburing#1509, but it does not include the fix.

This breaks CMSG uses of recvmsg through io_uring.

This and multiple other io_uring issues are fixed by recent upstream back ports: https://web.git.kernel.org/pub/scm/linux/kernel/git/axboe/stable.git/log/?h=6.17-stable

Hello @chrisvest ,
As I see your workflow failed 2 weeks ago, since then we have updated the kernel in the latest image release ubuntu24/20260406.80 with Kernel Version: 6.17.0-1010-azure.

Could you please check whether the issue still persists on your end? Just run your workflow again.
