  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Fix potential UAF when reading bpf link info  In bpf_link_show_fdinfo and bpf_link_get_info_by_fd, link-\u003eprog is accessed without holding any locks. If the prog is concurrently replaced via bpf_link_update, the old prog can be freed, leading to a potential UAF issue.  Fix this by accessing link-\u003eprog under RCU protection to safely fetch the pointer and guarantee its lifetime while reading its fields.",
