CVE-2022-50446 is a memory leakage vulnerability in the Linux kernel affecting all ARC CPUs, introduced in kernel stable release v5.15-rc1. The flaw stems from an incorrect handling of page table entries (PTEs) during process termination, where allocated memory for PTEs is not properly released. With a CVSS score of 5.5 (Medium), this local vulnerability (AV:L) has low attack complexity (AC:L) and requires low privileges (PR:L), leading to high availability impact (A:H) as repeated memory allocation can exhaust system resources. There is no evidence of active exploitation, nor are there publicly available exploit tools like Metasploit or Nuclei modules, and it has garnered minimal community discussion or media coverage.
