Linux Kernel Vulnerability in ext4 Affects Memory Management

CVE-2022-50622

What is CVE-2022-50622?

A memory leak vulnerability has been identified in the ext4 file system of the Linux kernel. This issue arises in the function handling the tracking of modified inodes due to an improper handling of memory allocation. When the krealloc function returns a NULL value, the previously allocated memory for the modified inode tracking is not released, leading to potential memory leaks. This vulnerability requires monitoring and remediation to prevent resource exhaustion and ensure system stability.
