kernel: nfsd: don't free session slots that are still in use

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. A remote attacker could exploit a use-after-free vulnerability in the nfsd4sequence function. This occurs when the system attempts to reduce the number of active session slots while a client is still using one of the slo...

kernel: NFSD: Prevent client use-after-free during blocked-lock reaping

A flaw was found in the Linux kernel's Network File System Daemon NFSD. A use-after-free vulnerability can occur during the blocked-lock reaping process. This happens when a client's lock owner, without a proper reference to keep the client alive, leads to the client being prematurely freed. This...
