Linux Kernel - Use-After-Free in NFS Server Cache Handling

Title source: llm
STIX 2.1

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.
