CVE-2026-110712 1 Sahlberg 1 Libsmb2 2026-11-10 6.5 Medium
libsmb2 through 6.2 contains a heap out-of-bounds read vulnerability in smb2_decode_file_all_info that allows malicious SMB servers to crash clients by sending an unchecked FileNameLength. Attackers controlling the server or performing man-in-the-middle on unsigned sessions can return crafted FileAllInformation replies to smb2_stat or smb2_fstat calls, crashing the client.
CVE-2026-110713 1 Sahlberg 1 Libsmb2 2026-11-10 6.5 Medium
libsmb2 through 6.2 contains a heap out-of-bounds read vulnerability in smb2_decode_file_fs_volume_info and smb2_decode_file_fs_attribute_info that allows malicious SMB servers to read past reply buffers. Attackers controlling a server or intercepting unsigned sessions can send crafted QUERY_INFO replies with missing or oversized name lengths to crash the client.
CVE-2026-110714 1 Sahlberg 1 Libsmb2 2026-11-10 6.5 Medium
libsmb2 through 6.2 contains an integer underflow vulnerability in decode_acl 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 QUERY_INFO reply, bypassing ACE bounds checks and crashing the client.
CVE-2026-115505 1 Sahlberg 1 Libsmb2 2026-10-29 7.6 High
libsmb2 before 6.3 contains integer overflow vulnerabilities in the DCE/RPC NDR decoder in lib/dcerpc.c that allow heap out-of-bounds reads and writes. A malicious SMB server or machine-in-the-middle on unsigned connections can send crafted NetrShareEnum replies with wrapping actual_count or max_count values when clients call smb2_share_enum_async(), corrupting heap memory.
