Description
In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-axi-dmac: do not print NULL LLI during error During debugging we have seen an issue where axi_chan_dump_lli() is passed a NULL LLI pointer which ends up causing an OOPS due to trying to get fields from it. Simply print NULL LLI and exit to avoid this.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability occurs in the Linux kernel's dmaengine component, specifically in the dw-axi-dmac driver. During debugging, the function axi_chan_dump_lli() is called with a NULL LLI (Linked List Item) pointer, which causes a kernel OOPS (crash) because the code tries to access fields from a NULL pointer. The fix is to detect the NULL LLI and print a message instead of causing a crash.


How can this vulnerability impact me? :

This vulnerability can cause the Linux kernel to crash (OOPS) during debugging when a NULL LLI pointer is accessed. This could lead to system instability or downtime if the affected code path is triggered.
