CVE-2026-90217

This Linux kernel BPF verifier vulnerability (CVE-2026-90217) occurs because an iterator stack slot can hold either MEM_RCU or PTR_UNTRUSTED pointer types, and the verifier fails to distinguish them during state pruning, potentially pruning an unsafe path. The fix compares the pointer type for ST...
