DEBIAN-CVE-2026-89703

In the Linux kernel, the following vulnerability has been resolved:  nfsd: set SCSTATUSFREED in nfsd4droprevokedstid for delegations  nfsd4droprevokedstid() handles FREESTATEID for admin-revoked delegations but does not set SCSTATUSFREED before releasing cllock. revokedelegation() uses this flag to detect whether FREESTATEID has already processed the delegation -- without it, the freed delegation is added to clrevoked via listadd(), producing a use-after-free when clrevoked is later traversed in destroyclient().  The SCSTATUSREVOKED path in nfsd4freestateid() (line 7983) already sets SCSTATUSFREED correctly. Apply the same pattern to the SCSTATUSADMINREVOKED path in nfsd4droprevokedstid().
