FKIE_CVE-2024-47737

Vulnerability from fkie_nvd - Published: 2024-10-21 13:15 - Updated: 2026-06-17 07:57
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: nfsd: call cache_put if xdr_reserve_space returns NULL If not enough buffer space available, but idmap_lookup has triggered lookup_fn which calls cache_get and returns successfully. Then we missed to call cache_put here which pairs with cache_get. Reviwed-by: Jeff Layton <jlayton@kernel.org>
