中文标题:
Linux kernel 安全漏洞
英文标题:
i2c: qup: jump out of the loop in case of timeout
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，该漏洞源于未正确处理超时，可能导致拒绝服务。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: i2c: qup: jump out of the loop in case of timeout Original logic only sets the return value but doesn't jump out of the loop if the bus is kept active by a client. This is not expected. A malicious or buggy i2c client can hang the kernel in this case and should be avoided. This is observed during a long time test with a PCA953x GPIO extender. Fix it by changing the logic to not only sets the return value, but also jumps out of the loop and return to the caller with -ETIMEDOUT.
