CVE-2023-53716

CVE-2023-53716 is a Linux kernel vulnerability described as a leak in skb handling: after a TX timestamp code path, if skb_orphan_frags_rx() fails, the skb cloned for zerocopy skb leaks. The issue is tied to the net: skb_tstamp_tx() flow and was addressed by a kernel fix in the commit that added ...

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...
