CVE-2025-68744

CVE-2025-68744 is a Linux kernel vulnerability affecting BPF maps. The issue arises from not freeing memory for BPF_KPTR_{REF,PERCPU} fields when updating certain lru_percpu_hash maps, potentially causing references to remain after map destruction. The root cause, as described in the initial CVE ...
