Null Dereference Vulnerability in Linux Kernel Affecting Task Memory Access

CVE-2022-50502

What is CVE-2022-50502?

A vulnerability in the Linux kernel's memory management system has been identified, specifically in the '/proc/pid/smaps_rollup' function. This issue arises when there are no virtual memory areas (VMAs) associated with a task, leading to a null dereference during execution. This situation can potentially disrupt the task management and memory access in systems running affected versions of the Linux kernel, necessitating prompt updates to mitigate risks.
