CVE-2026-90247

CVE-2026-90247 affects the Linux kernel BPF subsystem . The vulnerability resides in the per-CPU mmap_unlock_work irq_work slot shared by stack_map_get_build_id_offset() and bpf_find_vma(). Because both callers only check whether the work is busy before taking mmap_lock, a nested caller can reuse...
