CVE-2022-49343

CVE-2022-49343 (Linux kernel ext4) : A vulnerability in the ext4 filesystem’s h-tree directory structure allows cycles to exist in a directory’s h-tree, which can cause the kernel to access unallocated memory during a node split when traversing blocks. The root cause is that a corrupted filesyste...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from ext4 not verifying that block numbers in the directory h-tree are unique, which could lead to memory corruption...
