{"id":"DEBIAN-CVE-2024-35901","details":"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.
