Vulnerability from github – Published: 2026-03-25 12:30 – Updated: 2026-03-25 12:30

Details

In the Linux kernel, the following vulnerability has been resolved:

ice: change XDP RxQ frag_size from DMA write length to xdp.frame_sz

The only user of frag_size field in XDP RxQ info is bpf_xdp_frags_increase_tail(). It clearly expects whole buff size instead of DMA write size. Different assumptions in ice driver configuration lead to negative tailroom.

This allows to trigger kernel panic, when using XDP_ADJUST_TAIL_GROW_MULTI_BUFF xskxceiver test and changing packet size to 6912 and the requested offset to a huge value, e.g. XSK_UMEM__MAX_FRAME_SIZE * 100.

Due to other quirks of the ZC configuration in ice, panic is not observed in ZC mode, but tailroom growing still fails when it should not.

Use fill queue buffer truesize instead of DMA write size in XDP RxQ info. Fix ZC mode too by using the new helper.

Title

Summary

In the Linux kernel, the following vulnerability has been resolved: ice: change XDP RxQ frag_size from DMA write length to xdp.frame_sz The only user of frag_size field in XDP RxQ info is bpf_xdp_frags_increase_tail(). It clearly expects whole buff size instead of DMA write size. Different assumptions in ice driver configuration lead to negative tailroom. This allows to trigger kernel panic, when using XDP_ADJUST_TAIL_GROW_MULTI_BUFF xskxceiver test and changing packet size to 6912 and the requested offset to a huge value, e.g. XSK_UMEM__MAX_FRAME_SIZE * 100. Due to other quirks of the ZC configuration in ice, panic is not observed in ZC mode, but tailroom growing still fails when it should not. Use fill queue buffer truesize instead of DMA write size in XDP RxQ info. Fix ZC mode too by using the new helper.
