CVE-2023-53354

CVE-2023-53354 concerns the Linux kernel skb_segment path used for zero-copy of SKBs. The bug occurs when skb_orphan_frags() updates nr_frags, leaving the local nrfrags stale and causing a panic while iterating frags during GSO/zero-copy processing. The fix moves the call to zero-copy functions b...
