CVE-2025-21980 sched: address a potential NULL pointer dereference in the GRED scheduler.

In the Linux kernel, the following vulnerability has been resolved: sched: address a potential NULL pointer dereference in the GRED scheduler. If kzalloc in gredinit returns a NULL pointer, the code follows the error handling path, invoking greddestroy. This, in turn, calls gredoffload, where...

CVE-2025-21965

CVE-2025-21965 affects the Linux kernel sched_ext path used with BPF schedulers. If a BPF scheduler provides an invalid CPU (outside nr_cpu_ids) as prev_cpu to scx_bpf_select_cpu_dfl(), it can crash the kernel. The fix validates prev_cpu in scx_bpf_select_cpu_dfl() and triggers an scx error for i...
