Vulnerability CVE-2022-0185

Vulnerability Name:

CVE-2022-0185 (CCN-217455)

Assigned:

2022-01-18

Published:

2022-01-18

Updated:

2023-06-26

Summary:

Linux Kernel is vulnerable to a heap-based buffer overflow, caused by an integer underflow in the legacy_parse_param function in fs/fs_context.c. By sending a specially-crafted request, a local authenticated attacker could overflow a buffer and execute arbitrary code on the system with root privileges.
