UBUNTU-CVE-2022-50679

In the Linux kernel, the following vulnerability has been resolved: i40e: Fix DMA mappings leak During reallocation of RX buffers, new DMA mappings are created for those buffers. steps for reproduction: while : do for i=0; i=8160; i=i+32 do ethtool -G enp130s0f0 rx $i tx $i sleep 0.5 ethtool -g...

CVE-2022-50679

CVE-2022-50679 concerns the Linux kernel i40e driver, where DMA mappings leak during RX buffer reallocation. The root cause is that new DMA mappings are created for buffers when reconfiguring RX rings, leading to leaks when old buffers are freed and DMA mappings are freed incorrectly. This can ca...
