Title
net: mana: Fix Rx DMA datasize and skb_over_panic
Summary
In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix Rx DMA datasize and skb_over_panic mana_get_rxbuf_cfg() aligns the RX buffer's DMA datasize to be multiple of 64. So a packet slightly bigger than mtu+14, say 1536, can be received and cause skb_over_panic. Sample dmesg: [ 5325.237162] skbuff: skb_over_panic: text:ffffffffc043277a len:1536 put:1536 head:ff1100018b517000 data:ff1100018b517100 tail:0x700 end:0x6ea dev:<NULL> [ 5325.243689] ------------[ cut here ]------------ [ 5325.245748] kernel BUG at net/core/skbuff.c:192!

To fix this bug, remove it from the code. So oversized packets will be marked as CQE_RX_TRUNCATED by NIC, and dropped.

On the very common Azure configuration where the VM MTU is set below the path MTU (VPN Gateway / ExpressRoute / AKS overlay guidance), ordinary full-size internet packets fall directly into the oversized window.\nAC:L - The attacker fully controls the only variable that matters \u2014 packet length \u2014 and can simply sweep sizes until one lands in the (mtu+14, ALIGN(mtu+14,64)] window, which is non-empty for the default MTU 1500. No race, no memory-layout grooming, and no state outside the attacker\u0027s control is involved.\nPR:N - No authentication or credentials of any kind are needed; the panic occurs in mana_build_skb() before eth_type_trans() and before netfilter, so the frame need not even be addressed to a listening service or survive a firewall rule. Any unauthenticated party able to send a frame to the interface triggers it.\nUI:N - Triggering requires only that the victim\u0027s interface be up and receiving; the panic happens in softirq context during normal packet reception with no action by any local user or administrator.\nS:U - The vulnerable code and the impacted resource are both the host kernel \u2014 a standard in-kernel crash with no crossing of a VM, IOMMU, or sandbox security authority.\nC:N - No data is disclosed to the attacker: the overlong DMA writes the attacker\u0027s own packet bytes into the buffer\u0027s skb_shared_info scratch area within the same allocation, and skb_over_panic() aborts immediately, so no kernel memory is read back or leaked over the wire.\nI:N - The excess DMA stays inside the allocated page/fragment, targets a region that is not a live object at DMA time and is re-zeroed by napi_build_skb(), and every packet reaching it hits the unconditional BUG() in the same call path \u2014 so no adjacent object is corrupted and no write primitive is obtained.\nA:H - skb_put() detects tail \u003e end and calls skb_over_panic() \u2192 BUG() from within NAPI/softirq context, producing a fatal exception in interrupt and a full kernel panic. A single crafted packet takes the machine down, and it can be repeated at will against every affected Azure VM."

No race, no memory-layout grooming, and no state outside the attacker\u0027s control is involved.\\nPR:N - No authentication or credentials of any kind are needed; the panic occurs in mana_build_skb() before eth_type_trans() and before netfilter, so the frame need not even be addressed to a listening service or survive a firewall rule. Any unauthenticated party able to send a frame to the interface triggers it.\\nUI:N - Triggering requires only that the victim\u0027s interface be up and receiving; the panic happens in softirq context during normal packet reception with no action by any local user or administrator.\\nS:U - The vulnerable code and the impacted resource are both the host kernel \\u2014 a standard in-kernel crash with no crossing of a VM, IOMMU, or sandbox security authority.\\nC:N - No data is disclosed to the attacker: the overlong DMA writes the attacker\u0027s own packet bytes into the buffer\u0027s skb_shared_info scratch area within the same allocation, and skb_over_panic() aborts immediately, so no kernel memory is read back or leaked over the wire.\\nI:N - The excess DMA stays inside the allocated page/fragment, targets a region that is not a live object at DMA time and is re-zeroed by napi_build_skb(), and every packet reaching it hits the unconditional BUG() in the same call path \\u2014 so no adjacent object is corrupted and no write primitive is obtained.\\nA:H - skb_put() detects tail \u003e end and calls skb_over_panic() \\u2192 BUG() from within NAPI/softirq context, producing a fatal exception in interrupt and a full kernel panic. A single crafted packet takes the machine down, and it can be repeated at will against every affected Azure VM.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2fbbd712baf1c60996554326728bbdbef5616e12\", \"lessThan\": \"ca58927b00385005f488b6a9905ced7a4f719aad\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"2fbbd712baf1c60996554326728bbdbef5616e12\", \"lessThan\": \"05cb7c41fa1a7a7b2c2a6b81bbe7c67f5c11932b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"2fbbd712baf1c60996554326728bbdbef5616e12\", \"lessThan\": \"c0de6ab920aafb56feab56058e46b688e694a246\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/net/ethernet/microsoft/mana/mana_en.c\", \"include/net/mana/mana.h\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.4\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.4\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.26\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/net/ethernet/microsoft/mana/mana_en.c\", \"include/net/mana/mana.h\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/ca58927b00385005f488b6a9905ced7a4f719aad\"}, {\"url\": \"https://git.kernel.org/stable/c/05cb7c41fa1a7a7b2c2a6b81bbe7c67f5c11932b\"}, {\"url\": \"https://git.kernel.org/stable/c/c0de6ab920aafb56feab56058e46b688e694a246\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnet: mana: Fix Rx DMA datasize and skb_over_panic\\n\\nmana_get_rxbuf_cfg() aligns the RX buffer\u0027s DMA datasize to be\\nmultiple of 64.
