CVE-2024-47737
"NFSd Unprotected Cache Reference"
Description
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 <[email protected]>
