A vulnerability in the Linux kernel's kcm subsystem involves improper use of plain stores when changing lower socket callbacks, leading to potential stale or misdirected wakeups due to concurrency issues. The flaw arises because callback-pointer updates in kcm_attach() and kcm_unattach() are not protected with WRITE_ONCE(), causing visibility problems across CPUs. This issue has been resolved by using WRITE_ONCE() to ensure proper memory visibility and synchronization of callback updates.
