| "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's DMA datasize to be\nmultiple of 64. So a packet slightly bigger than mtu+14, say 1536,\ncan be received and cause skb_over_panic.\n\nSample dmesg:\n[ 5325.237162] skbuff: skb_over_panic: text:ffffffffc043277a len:1536 put:1536 head:ff1100018b517000 data:ff1100018b517100 tail:0x700 end:0x6ea dev:<NULL>\n[ 5325.243689] ------------[ cut here ]------------\n[ 5325.245748] kernel BUG at net/core/skbuff.c:192!\n[ 5325.247838] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI\n[ 5325.258374] RIP: 0010:skb_panic+0x4f/0x60\n[ 5325.302941] Call Trace:\n[ 5325.304389] <IRQ>\n[ 5325.315794] ? skb_panic+0x4f/0x60\n[ 5325.317457] ? asm_exc_invalid_op+0x1f/0x30\n[ 5325.319490] ? skb_panic+0x4f/0x60\n[ 5325.321161] skb_put+0x4e/0x50\n[ 5325.322670] mana_poll+0x6fa/0xb50 [mana]\n[ 5325.324578] __napi_poll+0x33/0x1e0\n[ 5325.326328] net_rx_action+0x12e/0x280\n\nAs discussed internally, this alignment is not necessary.
