CVE-2026-98452 smb: client: clean up failed cached directory opens

In the Linux kernel, the following vulnerability has been resolved: smb: client: clean up failed cached directory opens opencacheddir sends CREATE and QUERYINFO as a compound request. If the CREATE succeeds but a later command returns an error, the function must retain the CREATE FID so common...

CVE-2026-110714

libsmb2 through 6.2 contains an integer underflow vulnerability in decodeacl that allows malicious SMB servers to trigger heap out-of-bounds reads via crafted security descriptors. Attackers controlling a server or intercepting unsigned sessions can send an AclSize below 8 in a QUERYINFO reply,...

CVE-2026-110713

libsmb2 through 6.2 contains a heap out-of-bounds read vulnerability in smb2decodefilefsvolumeinfo and smb2decodefilefsattributeinfo that allows malicious SMB servers to read past reply buffers. Attackers controlling a server or intercepting unsigned sessions can send crafted QUERYINFO replies wi...

CVE-2026-110714

The libsmb2 library, versions through 6.2 , is vulnerable to a heap out-of-bounds read caused by an integer underflow in the decode_acl function. A malicious SMB server or an attacker intercepting an unsigned session can trigger this by sending a crafted QUERY_INFO reply with an AclSize value bel...

CVE-2026-110713 libsmb2 through 6.2 Heap Out-of-Bounds Read via File System Info Decoders

libsmb2 through 6.2 contains a heap out-of-bounds read vulnerability in smb2decodefilefsvolumeinfo and smb2decodefilefsattributeinfo that allows malicious SMB servers to read past reply buffers. Attackers controlling a server or intercepting unsigned sessions can send crafted QUERYINFO replies wi...

CVE-2026-110713

The libsmb2 library through version 6.2 is vulnerable to a heap out-of-bounds read in the smb2_decode_file_fs_volume_info and smb2_decode_file_fs_attribute_info functions. This flaw occurs because malicious SMB servers can send crafted QUERY_INFO replies with oversized or missing name lengths, ca...
