CVE-2023-54220 (CNNVD-202512-5237)
中文标题:
Linux kernel 安全漏洞
英文标题:
serial: 8250: Fix oops for port->pm on uart_change_pm()
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于端口电源管理函数未正确清除，可能导致内核页错误。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix oops for port->pm on uart_change_pm() Unloading a hardware specific 8250 driver can produce error "Unable to handle kernel paging request at virtual address" about ten seconds after unloading the driver. This happens on uart_hangup() calling uart_change_pm(). Turns out commit 04e82793f068 ("serial: 8250: Reinit port->pm on port specific driver unbind") was only a partial fix. If the hardware specific driver has initialized port->pm function, we need to clear port->pm too. Just reinitializing port->ops does not do this. Otherwise serial8250_pm() will call port->pm() instead of serial8250_do_pm().
