Details

In the Linux kernel, the following vulnerability has been resolved:

soc: ti: pruss: Fix double free in pruss_clk_mux_setup()

In the pruss_clk_mux_setup(), the devm_add_action_or_reset() indirectly calls pruss_of_free_clk_provider(), which calls of_node_put(clk_mux_np) on the error path. However, after the devm_add_action_or_reset() returns, the of_node_put(clk_mux_np) is called again, causing a double free.

Fix by returning directly, to avoid the duplicate of_node_put().

Severity ?
7.8 (High)
