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.
