Official Description

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().

Technical Analysis

CVE-2026-43196 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
