CVE-2023-53472 (CNNVD-202510-128)
中文标题:
Linux kernel 安全漏洞
英文标题:
pwm: lpc32xx: Remove handling of PWM channels
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，该漏洞源于未检查pwm-hwpwm值，可能导致空指针取消引用。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: pwm: lpc32xx: Remove handling of PWM channels Because LPC32xx PWM controllers have only a single output which is registered as the only PWM device/channel per controller, it is known in advance that pwm->hwpwm value is always 0. On basis of this fact simplify the code by removing operations with pwm->hwpwm, there is no controls which require channel number as input. Even though I wasn't aware at the time when I forward ported that patch, this fixes a null pointer dereference as lpc32xx->chip.pwms is NULL before devm_pwmchip_add() is called.
