CVE-2026-46256

CVE-2026-46256 refers to a Linux kernel flaw in the NFS LOCALIO optimization. The issue allows a recursion deadlock during direct reclaim when writing pages back into NFS via nfs_writepages, potentially affecting NFS loopback paths where LOCALIO is used on the same system. The root cause is that ...

CVE-2026-46124

A flaw was found in the Linux kernel's isofs filesystem. An authenticated NFS Network File System peer can exploit this vulnerability by providing a specially crafted file handle. This allows the server to read arbitrary in-range blocks on the backing device, leading to information disclosure whe...

CVE-2026-46124

CVE-2026-46124 affects the Linux kernel isofs filesystem. The vulnerability arises because isofs_fh_to_dentry/isofs_fh_to_parent pass an attacker-controlled block number from an NFS file handle to isofs_export_iget(), which only rejects block == 0 before calling isofs_iget and sb_bread. A crafted...
