SUSE CVE-2026-89678

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix partial-write detection in nfsddirectwrite nfsddirectwrite walks a list of write segments and, after each vfsiocbiterwrite, tries to detect a short write so the loop can stop before placing the next segment at a wrong...

CVE-2026-89678

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd component. The nfsddirectwrite function, responsible for handling direct writes, incorrectly detects partial writes. This issue occurs because the logic for detecting short writes compares the actual bytes written against ...

CVE-2026-89678 nfsd: fix partial-write detection in nfsd_direct_write

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix partial-write detection in nfsddirectwrite nfsddirectwrite walks a list of write segments and, after each vfsiocbiterwrite, tries to detect a short write so the loop can stop before placing the next segment at a wrong...

CVE-2026-89678

CVE-2026-89678 is a flaw in the Linux kernel's nfsd (NFS server daemon), specifically in the nfsd_direct_write() function. The partial-write detection logic compares host_err against segments[i].iter.count, which has already been advanced by vfs_iocb_iter_write() to the residual (original length ...
