In the Linux kernel, the following vulnerability has been resolved: nfs: Handle error of rpcprocregister in nfsnetinit. syzkaller reported a warning 0 triggered while destroying immature netns. rpcprocregister was called in initnfsfs, but its error has been ignored since at least the initial comm...

CVE-2021-47260

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix a potential NULL dereference in nfsgetclient None of the callers are expecting NULL returns from nfsgetclient so this code will lead to an Oops. It's better to return an error pointer. I expect that this is dead code so...

CVE-2021-47259

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix use-after-free in nfs4initclient KASAN reports a use-after-free when attempting to mount two different exports through two different NICs that belong to the same server. Olga was able to hit this with kernels starting...

CVE-2021-47259

CVE-2021-47259 is a Linux kernel use-after-free in NFS: nfs4_init_client. Public docs confirm KASAN-detected UAF when mounting two exports via two NICs on the same server; affected kernels include around 5.7–5.10 with the root cause linked to refcounting changes. The connected Astra/Unity/EulerOS...

CVE-2024-27031

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix nfsnetfsissueread xarray locking for writeback interrupt The loop inside nfsnetfsissueread currently does not disable interrupts while iterating through pages in the xarray to submit for NFS read. This is not safe though...

CVE-2024-27031

CVE-2024-27031 (Linux kernel) : The NFS read path (nfs_netfs_issue_read) locked with xa_lock while submitting pages for writeback, but did not disable interrupts during iteration, creating a deadlock risk if an interrupt runs and touches the xa_lock. The fix replaces manual iteration with xa_for_...

In the Linux kernel, the following vulnerability has been resolved: NFS: Don't corrupt the value of pgbyteswritten in nfsdorecoalesce The value of mirror-pgbyteswritten should only be updated after a successful attempt to flush out the requests on the list...

CVE-2021-47167

CVE-2021-47167 is a Linux kernel issue affecting NFS: an Oopsable condition in __nfs_pageio_add_request() could occur. The patch ensures that nfs_pageio_error_cleanup() resets the mirror array contents so the structure reflects an empty state, and it makes nfs_pageio_do_add_request() more robust ...
