CVE-2021-47422 is a memory leak vulnerability (CWE-401) in the Linux kernel's Nouveau display driver (drm/nouveau/kms/nv50-). Specifically, it occurs when single_open() is used without a corresponding single_release(), leading to leaked memory. Rated Medium severity (CVSS 5.5), this vulnerability requires local access (AV:L/PR:L) and has low attack complexity (AC:L). While it doesn't impact confidentiality or integrity (C:N/I:N), it can lead to a high impact on availability (A:H) due to resource exhaustion. There is no evidence of active exploitation, nor are there publicly available exploits in Metasploit or ExploitDB. The vulnerability has received minimal community discussion and media coverage, indicating low public attention.
