CVE-2024-40909

The Linux kernel vulnerability related to bpf_link_free() involved a potential use-after-free condition. After commit 1a80dbcb2dba, the bpf_link could be freed via link->ops->dealloc_deferred, but the code erroneously continued to reference link->ops->dealloc. This dual reference risked accessing freed memory, leading to undefined behavior.
