AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a double free issue in the Linux kernel's pruss_clk_mux_setup() function within the TI PRUSS subsystem.
Specifically, the function devm_add_action_or_reset() indirectly calls pruss_of_free_clk_provider(), which calls of_node_put(clk_mux_np) on an error path. After devm_add_action_or_reset() returns, of_node_put(clk_mux_np) is called again, causing the same resource to be freed twice.
The fix involves returning directly to avoid calling of_node_put() a second time, thus preventing the double free.
How can this vulnerability impact me? :
This vulnerability involves a double free error in the Linux kernel's pruss_clk_mux_setup() function. A double free can potentially lead to memory corruption, which might be exploited to cause system instability or crashes.
However, the CVE description does not provide specific details on the impact beyond the double free issue, such as whether it can be exploited for privilege escalation or remote code execution.
What immediate steps should I take to mitigate this vulnerability?
The vulnerability is fixed in the Linux kernel by correcting the double free issue in the pruss_clk_mux_setup() function. To mitigate this vulnerability, you should update your Linux kernel to a version that includes this fix.
