Kernel: use-after-free in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c

A use-after-free flaw was found in nfsd4sscsetupdul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem...

SUSE CVE-2025-38028

In the Linux kernel, the following vulnerability has been resolved: NFS/localio: Fix a race in nfslocalopenfh Once the clp-cluuid.lock has been dropped, another CPU could come in and free the struct nfsdfile that was just added. To prevent that from happening, take the RCU read lock before droppi...

kernel: nfsd: return -EINVAL when namelen is 0

In the Linux kernel, the following vulnerability has been resolved: nfsd: return -EINVAL when namelen is 0 When we have a corrupted main.sqlite in /var/lib/nfs/nfsdcld/, it may result in namelen being 0, which will cause memdupuser to return ZEROSIZEPTR. When we access the name.data that has been...

kernel: nfsd: make sure exp active before svc_export_show

In the Linux kernel, the following vulnerability has been resolved: nfsd: make sure exp active before svcexportshow The function eshow was called with protection from RCU. This only ensures that exp will not be freed. Therefore, the reference count for exp can drop to zero, which will trigger a...

kernel: nfsd: map the EBADMSG to nfserr_io to avoid warning

In the Linux kernel, the following vulnerability has been resolved: nfsd: map the EBADMSG to nfserrio to avoid warning Ext4 will throw -EBADMSG through ext4readdir when a checksum error occurs, resulting in the following WARNING. Fix it by mapping EBADMSG to nfserrio. nfsdbufferedreaddir iterated...
