CVE-2024-50159

In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Fix the double free in scmi_debugfs_common_setup() Clang static checker(scan-build) throws below warning： | drivers/firmware/arm_scmi/driver.c:line 2915, column 2 | Attempt to free released memory. When devm_add_action_or_reset() fails, scmi_debugfs_common_cleanup() will run twice which causes double free of 'dbg->name'. Remove the redundant scmi_debugfs_common_cleanup() to fix this problem.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firmware: arm_scmi: Se corrige la doble liberación en scmi_debugfs_common_setup() El verificador estático de Clang (scan-build) arroja la siguiente advertencia: \| drivers/firmware/arm_scmi/driver.c:line 2915, column 2 \| Intenta liberar la memoria liberada. Cuando devm_add_action_or_reset() falla, scmi_debugfs_common_cleanup() se ejecutará dos veces, lo que provoca una doble liberación de 'dbg->name'. Elimina el scmi_debugfs_common_cleanup() redundante para solucionar este problema.
