英文标题:
staging: vt6655: fix some erroneous memory clean-up loops
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，该漏洞源于内存清理循环错误，可能导致内存泄漏和无效内存访问。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: staging: vt6655: fix some erroneous memory clean-up loops In some initialization functions of this driver, memory is allocated with 'i' acting as an index variable and increasing from 0. The commit in "Fixes" introduces some clean-up codes in case of allocation failure, which free memory in reverse order with 'i' decreasing to 0. However, there are some problems: - The case i=0 is left out. Thus memory is leaked. - In case memory allocation fails right from the start, the memory freeing loops will start with i=-1 and invalid memory locations will be accessed. One of these loops has been fixed in commit c8ff91535880 ("staging: vt6655: fix potential memory leak"). Fix the remaining erroneous loops.
