Description (Chinese)
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ext4_clu_mapped函数在bigalloc和inline选项同时启用时错误搜索不存在的extent树，可能导致无效的extent状态缓存、错误的保留集群计数、内存泄漏和内核崩溃。
Description (English)
Linux Kernel is the kernel used by Linux, the Open Source Operator System of the Linux Foundation of the United States. Linux Kernel has a security loophole, which stems from the error of the ext4 clu mapped function to search for non-existent extent trees when the bigalloc and inline options are enabled, which could lead to invalid extent status caches, incorrect retention cluster counts, memory leaks and kernel crashes.
