      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: fix pedit partial COW leading to page cache corruption\n\ntcf_pedit_act() computes the COW range for skb_ensure_writable()\nonce before the key loop using tcfp_off_max_hint, but the hint does\nnot account for the runtime header offset added by typed keys. This\ncan leave part of the write region un-COW'd.\n\nFix by moving skb_ensure_writable() inside the per-key loop where\nthe actual write offset is known, and add overflow checking on the\noffset arithmetic. For negative offsets (e.g. Ethernet header edits\nat ingress), use skb_cow() to COW the headroom instead. Guard\noffset_valid() against INT_MIN, where negation is undefined.",
