CVE-2022-50023

The CVE-2022-50023 issue affects the Linux kernel's DMAengine dw-axi-dmac component. When a channel has no descriptor and an interrupt is raised, the kernel can OOPS. The root cause is not validating the descriptor result; the fix is to check the outcome of vchan_next_desc() in axi_chan_block_xfe...

CVE-2022-49683

The CVE-2022-49683 entry concerns the Linux kernel, specifically the IIO ADC driver for adi-axi-adc. The root cause is a refcount leak where of_parse_phandle() returns a node pointer with an incremented refcount, and the patch adds a missing of_node_put() when the node is no longer needed. The ch...
