nfs-ganesha: CVE-2026-105517

Severity: High · CVSS 8.1CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Published: Oct 5, 2026, 12:00:00 AM UTC
Source: [NVD] · [CVE record]

A use-after-free vulnerability was found in the 9P protocol implementation of NFS-Ganesha. The server does not protect the lifetime of file identifier (FID) objects when processing concurrent requests. An attacker can race a write operation against a close operation on the same FID, causing one worker thread to free the FID and its associated data while another thread continues to use it. This allows attacker-controlled data to be written into freed heap memory, which can result in a crash or potentially remote code execution. The 9P protocol handler does not implement authentication, so the vulnerability is reachable without credentials by any client with network access to the 9P listener. nfs-ganesha: nfs-ganesha: 9P TWRITE/TCLUNK race condition use-after-free Red Hat's versions of nfs-ganesha do not compile the 9P protocol support, so this vulnerability does not affect any Red Hat products. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
