Description

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

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().

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
