CVE-2026-46139

CVE-2026-46139 covers the Linux kernel SMB client: when building an ACL descriptor in build_sec_desc(), a kzalloc-based allocation fix was introduced to zero-initialize the security descriptor buffer, replacing a previous kmalloc path. The change splits struct smb_acl's __le32 num_aces into __le1...

CVE-2026-46130

CVE-2026-46130 concerns the Linux kernel’s dm-verity-fec component. The root cause is an incorrect assumption about parity data layout: when reading parity bytes across blocks, parity bytes for the first RS codeword can be split across parity blocks, causing an out-of-bounds read under certain no...

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...
