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 ...

CVE-2026-80875

In the Linux kernel , the IPVS (IP Virtual Server) subsystem contained a bug in TCP state lookup for IPv6 packets. The code reparsed the socket buffer to locate the TCP header using a fixed offset of sizeof(struct ipv6hdr), rather than the already-computed transport-header offset stored in iph.le...

kernel: block: Fix wrong offset in bio_truncate()

In the Linux kernel, the following vulnerability has been resolved: block: Fix wrong offset in biotruncate biotruncate clears the buffer outside of last block of bdev, however current biotruncate is using the wrong offset of page. So it can return the uninitialized data. This happened when both o...
