漏洞归属组件:kernel
漏洞归属的版本:4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.12.33,6.18.18,6.18.40,6.18.48,6.4.0,6.6.0
CVSS评分:
BaseScore:9.8 Critical
Vector:CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:NFSD: Prevent client use-after-free during close_lru reapingAn nfs4_openowner left on nn->close_lru after its final CLOSE keepsits last closed stateid in oo_last_closed_stid, holding only a rawpointer to its nfs4_client. The laundromat reaps timed-out entries,drops nn->client_lock, and calls nfs4_put_stid(), which dereferencesthe client through cl_lock. Nothing pins the client across thatwindow, so a concurrent force_expire_client() can free it andnfs4_put_stid() reads freed memory. __destroy_client() hits the samerace, walking clp->cl_openowners without cl_lock.Pin the client with cl_rpc_users before dropping client_lock, andskip clients already expiring. __destroy_client() then cleans up itsown close_lru entries through release_last_closed_stateid(), soteardown no longer races the laundromat.
