CVE-2026-93229 nfsd: add missing read barrier to rpc_status_get dumpit seqcount retry

In the Linux kernel, the following vulnerability has been resolved: nfsd: add missing read barrier to rpcstatusget dumpit seqcount retry The hand-rolled seqcount-like protocol in nfsdnlrpcstatusgetdumpit is missing a read memory barrier smprmb before its second counter check. The standard kernel...

CVE-2026-93229

The Linux kernel is affected by a vulnerability in the nfsd component. Specifically, the hand-rolled seqcount-like protocol in nfsd_nl_rpc_status_get_dumpit() lacks a read memory barrier (smp_rmb) before its second counter check. On weakly-ordered architectures such as ARM and POWER , the CPU may...

CVE-2026-93221 nfsd: convert nfsd_net boolean flags to unsigned long flags word

In the Linux kernel, the following vulnerability has been resolved: nfsd: convert nfsdnet boolean flags to unsigned long flags word nfsdnet contains several boolean fields that are accessed from concurrent contexts without serialization. In particular, nfsd4endgrace guards its drain path with a...

CVE-2026-93221

The Linux kernel is vulnerable to a race condition in the nfsd component due to a lack of serialization when accessing boolean fields in nfsd_net. Specifically, the nfsd4_end_grace() function uses a plain boolean for grace_ended, allowing concurrent paths—such as the laundromat path and the RECLA...

CVE-2026-93212

A vulnerability exists in the Linux kernel nfsd service where a NULL pointer dereference occurs in nfsd_file_net_dispose(). During per-net teardown, nn->nfsd_serv is cleared before the filecache laundrette is shut down. This allows the service thread to execute a dispose pass that identifies e...
