CVE-2022-48690

Insight : CVE-2022-48690 refers to a Linux kernel fix in the ice driver for a DMA mappings leak when reallocating RX buffers while changing ring parameters. The leak occurred because kfree on rx_buf freed DMA mappings that were still active, leading to leaked DMA mappings during buffer substituti...

CVE-2022-48690 ice: Fix DMA mappings leak

In the Linux kernel, the following vulnerability has been resolved: ice: Fix DMA mappings leak Fix leak, when user changes ring parameters. During reallocation of RX buffers, new DMA mappings are created for those buffers. New buffers with different RX ring count should substitute older ones, but...
