SUSE CVE-2026-43074

In the Linux kernel, the following vulnerability has been resolved: eventpoll: defer struct eventpoll free to RCU grace period In certain situations, epfree in eventpoll.c will kfree the epi-ep eventpoll struct while it still being used by another concurrent thread. Defer the kfree to an RCU...

CVE-2026-43074

A flaw was found in the Linux kernel's eventpoll component. In certain situations, the epfree function in eventpoll.c can prematurely free the eventpoll data structure while it is still being used by another concurrent thread. This use-after-free UAF vulnerability could allow a local attacker to...

CVE-2026-43074

CVE-2026-43074 affects the Linux kernel eventpoll code. The vulnerability arises from ep_free() freeing the eventpoll structure while still in use by another thread, creating a use-after-free (UAF). The fix defers kfree() of the epi->ep struct to an RCU grace period to prevent UAF; multiple so...
