CVE-2023-54301 [LOW] CWE-772 kernel: serial: 8250_bcm7271: fix leak in `brcmuart_probe`
kernel: serial: 8250_bcm7271: fix leak in `brcmuart_probe`
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250_bcm7271: fix leak in `brcmuart_probe`
Smatch reports:
drivers/tty/serial/8250/8250_bcm7271.c:1120 brcmuart_probe() warn:
'baud_mux_clk' from clk_prepare_enable() not released on lines: 1032.
The issue is fixed by using a managed clock.
A resource leak flaw was found in the Broadcom BCM7271 serial driver. In the brcmuart_probe() function, the baud_mux_clk clock is prepared and enabled but not released in error paths, causing a clock resource leak when driver probe fails.
Statement: This affects only Broadcom BCM7271 platforms using the 8250_bcm7271 serial driver. The leak occurs only during failed probe operations, not during normal runtime. Standard
