The current CPU sync starts at\ndma_addr and only covers rx_bytes + MVPP2_MH_SIZE bytes, which syncs the\nunused headroom and misses the same number of bytes at the packet tail.\n\nOn non-coherent DMA systems this can leave the CPU reading stale cache\ncontents for the end of the received frame.\n\nUse dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range\noffset so the sync covers the Marvell header and packet data actually\nwritten by hardware."}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","baseScore":8.6,"baseSeverity":"HIGH"},"scenarios":[{"lang":"en","value":"AV:N - The vulnerable code is in the Ethernet RX path and is reached by packets received on an affected mvpp2 network interface. A remote peer can trigger it by sending network traffic to a system using this driver.\nAC:L - On affected non-coherent DMA deployments, exploitation only requires sending received frames that traverse the normal RX/NAPI path. There is no race or attacker-uncontrolled timing requirement in the vulnerable path.\nPR:N - No local privileges or authentication are required to reach the receive path. The attacker only needs network reachability to the affected interface.\nUI:N - Packet reception and processing happen automatically once the interface is up. No user action is required.\nS:U - The bug affects packet data handled within the same kernel/network-device security authority. It does not cross a VM, IOMMU, or other separate security boundary.\nC:H - The incorrect DMA sync can leave stale cache contents in the tail of received skbs, potentially exposing previous packet-buffer contents through delivery, forwarding, or reflection. Repeated remote triggering can disclose more than a few bounded bytes of network data over time.\nI:L - The CPU-visible packet tail can differ from the actual frame written by hardware, corrupting data delivered to XDP, the network stack, or applications. This is packet/data integrity loss, but not an arbitrary kernel memory write or control-flow primitive.\nA:L - An attacker can repeatedly cause corrupted received packets, leading to packet drops, protocol failures, or degraded network service. The investigated path does not indicate a kernel panic, hang, or reliable full-system DoS."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/marvell/mvpp2/mvpp2_main.c"],"versions":[{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"60412bdd1b2576659eac23a23d2d9ff96228a643","status":"affected","versionType":"git"},{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"19f8bc139e9b149d1e5bf75ae761d1bb8dd3e7d8","status":"affected","versionType":"git"},{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"a3ad9b5767c89531fc7dae951b51b0933dcf7051","status":"affected","versionType":"git"},{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"bede0f481b9137d73d1cf64309cbe4b94818a5d6","status":"affected","versionType":"git"},{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"23548007b3c66d628fc7d6b80d1e23be04ea10d9","status":"affected","versionType":"git"},{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"a13199fa224e9f776f4005d5037df03aa9ea8f37","status":"affected","versionType":"git"},{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"e302206ad84a407a7e5f3f6fe767ff5efaace689","status":"affected","versionType":"git"},{"version":"e1921168bbd4810de4197446e52f652cd0dd9541","lessThan":"180235600934bef6add3be637c296d6cf3272e67","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/marvell/mvpp2/mvpp2_main.c"],"versions":[{"version":"5.5","status":"affected"},{"version":"0","lessThan":"5.5","status":"unaffected","versionType":"semver"},{"version":"5.10.259","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.210","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.176","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.143","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.94","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.36","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.13","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"5.5","versionEndExcluding":"5.10.259"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.15.210"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.1.176"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.6.143"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.12.94"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.18.36"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"7.0.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/60412bdd1b2576659eac23a23d2d9ff96228a643"},{"url":"https://git.kernel.org/stable/c/19f8bc139e9b149d1e5bf75ae761d1bb8dd3e7d8"},{"url":"https://git.kernel.org/stable/c/a3ad9b5767c89531fc7dae951b51b0933dcf7051"},{"url":"https://git.kernel.org/stable/c/bede0f481b9137d73d1cf64309cbe4b94818a5d6"},{"url":"https://git.kernel.org/stable/c/23548007b3c66d628fc7d6b80d1e23be04ea10d9"},{"url":"https://git.kernel.org/stable/c/a13199fa224e9f776f4005d5037df03aa9ea8f37"},{"url":"https://git.kernel.org/stable/c/e302206ad84a407a7e5f3f6fe767ff5efaace689"},{"url":"https://git.kernel.org/stable/c/180235600934bef6add3be637c296d6cf3272e67"}],"title":"net: mvpp2: sync RX data at the hardware packet offset","x_generator":{"engine":"bippy-1.2.0"}}}}
