      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nice: change XDP RxQ frag_size from DMA write length to xdp.frame_sz\n\nThe only user of frag_size field in XDP RxQ info is\nbpf_xdp_frags_increase_tail(). It clearly expects whole buff size instead\nof DMA write size. Different assumptions in ice driver configuration lead\nto negative tailroom.\n\nThis allows to trigger kernel panic, when using\nXDP_ADJUST_TAIL_GROW_MULTI_BUFF xskxceiver test and changing packet size to\n6912 and the requested offset to a huge value, e.g.\nXSK_UMEM__MAX_FRAME_SIZE * 100.\n\nDue to other quirks of the ZC configuration in ice, panic is not observed\nin ZC mode, but tailroom growing still fails when it should not.\n\nUse fill queue buffer truesize instead of DMA write size in XDP RxQ info.\nFix ZC mode too by using the new helper.",
