CVE-2026-89713 NFSD: check truncate permission under inode lock

In the Linux kernel, the following vulnerability has been resolved: NFSD: check truncate permission under inode lock nfsdsetattr checks whether a size update needs NFSDMAYTRUNC before it takes inodelock. The comparison uses the file size sampled by that unlocked read, but the actual ATTRSIZE upda...

CVE-2026-89713

A TOCTOU race condition in the Linux kernel's NFS Daemon (NFSD) component allows a remote, unauthenticated attacker to bypass append-only file protections. In nfsd_setattr(), the NFSD_MAY_TRUNC permission check samples the file size without holding inode_lock(), but the actual size update is appl...

CVE-2026-89640 cifs: fix loff_t underflow in cifs_remap_file_range() when len == 0

In the Linux kernel, the following vulnerability has been resolved: cifs: fix lofft underflow in cifsremapfilerange when len == 0 With len == 0 clone to EOF, the effective length is computed as: len = srcinode-isize - off; If off isize, this is a negative lofft, corrupting the ByteCount in the...

CVE-2026-89640

CVE-2026-89640 is an integer underflow in the Linux kernel's CIFS filesystem driver, specifically in cifs_remap_file_range() when performing a remap with len == 0 (clone to EOF). If the offset exceeds the source file size, the computed length becomes a negative loff_t , corrupting the ByteCount i...
