CVE-2026-43196: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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().
