- The bug is in the Hisilicon HIX5HD2 Gigabit Ethernet MAC RX path (hix5hd2_rx), reached when frames arrive on the L2 Ethernet segment of hi3516a/hi3798cv200 and similar SoCs; an attacker must be on the same LAN/broadcast domain to deliver those frames, matching Adjacent scoring for Ethernet NIC RX UAFs of this class.\nAC:L - An adjacent peer can reliably force GRO merge (GRO_MERGED_FREE) by bursting same-flow TCP segments so napi_gro_receive() frees the skb before the immediate skb->len read; GRO is enabled by default via NETIF_F_SOFT_FEATURES and no attacker-uncontrollable race is required.\nPR:N - Frame delivery runs in softirq/NAPI with no host authentication or capability check; any unauthenticated peer that can put Ethernet frames on the wire triggers the path.\nUI:N - RX interrupt and NAPI processing run automatically once the interface is up; no victim action such as opening a file or confirming a prompt is required.\nS:U - The use-after-free corrupts host-kernel sk_buff heap state within the same OS security authority and does not cross a VM, IOMMU, or sandbox boundary.\nC:H - This is a heap use-after-free of an sk_buff after napi_gro_receive may free it; reclaiming the general-purpose slab object enables disclosure of reused kernel memory via the dangling skb->len read, scored High per UAF guidance.\nI:H - sk_buff use-after-free in a general-purpose slab is a classic heap-grooming primitive that can yield attacker-controlled object reuse and control-flow hijacking, so integrity impact is High per kernel UAF scoring guidance.\nA:H - Dereferencing a freed sk_buff can oops/panic the kernel, and an adjacent attacker can repeatedly inject frames to crash the host at will."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/hisilicon/hix5hd2_gmac.c"],"versions":[{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"179499e7a240b2ef590f05eb379c810c26bbc8a4","status":"affected","versionType":"git"},{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"8067cd244cea2c332f8326842fd10158fa2cb64f","status":"affected","versionType":"git"},{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"3a4eddd1cb023a71df4152fcc76092953e6fe95a","status":"affected","versionType":"git"},{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"1b6360a093ab8969c91a30bb58b753282e2ced4c","status":"affected","versionType":"git"},{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"93aaa4bb72e388f6a4887541fd3d18b84f1b5ddc","status":"affected","versionType":"git"},{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"b8ce0e6f9f88a6bb49d291498377e61ea27a5387","status":"affected","versionType":"git"},{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"b6307f7a2fc1c5407b6176f2af34a95214a8c262","status":"affected","versionType":"git"},{"version":"57c5bc9ad7d799e9507ba6e993398d2c55f03fab","lessThan":"433c07a13f59856e4585e89e86b7d4cc59348fab","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/hisilicon/hix5hd2_gmac.c"],"versions":[{"version":"3.16","status":"affected"},{"version":"0","lessThan":"3.16","status":"unaffected","versionType":"semver"},{"version":"4.9.336","lessThanOrEqual":"4.9.*","status":"unaffected","versionType":"semver"},{"version":"4.14.302","lessThanOrEqual":"4.14.*","status":"unaffected","versionType":"semver"},{"version":"4.19.269","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.227","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.159","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.83","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.0.13","lessThanOrEqual":"6.0.*","status":"unaffected","versionType":"semver"},{"version":"6.1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"4.9.336"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"4.14.302"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"4.19.269"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"5.4.227"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"5.10.159"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"5.15.83"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.0.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/179499e7a240b2ef590f05eb379c810c26bbc8a4"},{"url":"https://git.kernel.org/stable/c/8067cd244cea2c332f8326842fd10158fa2cb64f"},{"url":"https://git.kernel.org/stable/c/3a4eddd1cb023a71df4152fcc76092953e6fe95a"},{"url":"https://git.kernel.org/stable/c/1b6360a093ab8969c91a30bb58b753282e2ced4c"},{"url":"https://git.kernel.org/stable/c/93aaa4bb72e388f6a4887541fd3d18b84f1b5ddc"},{"url":"https://git.kernel.org/stable/c/b8ce0e6f9f88a6bb49d291498377e61ea27a5387"},{"url":"https://git.kernel.org/stable/c/b6307f7a2fc1c5407b6176f2af34a95214a8c262"},{"url":"https://git.kernel.org/stable/c/433c07a13f59856e4585e89e86b7d4cc59348fab"}],"title":"net:
