CVE-2024-47737

CVE-2024-47737 is a Linux kernel vulnerability in NFSD where, when xdr_reserve_space returns NULL due to insufficient buffer, a missing cache_put after a successful cache_get can occur if idmap_lookup triggers lookup_fn. This can create a mismatch in the nfsd cache handling. The CVE has a CVSSv3....
