| CVE-2026-4408 | Cri | 9.0 | < 4.19.4-16.el8_10 | 4.19.4-16.el8_10 | May 28, 2026 | A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed | |
| CVE-2026-2340 | Med | 6.5 | < 4.23.5-109.el10_2 | 4.23.5-109.el10_2 | May 27, 2026 | A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write | |

The SMB protocol allows opening files when the client reque | |
| CVE-2023-3347 | Med | 5.9 | < 4.17.5-103.el9_2.alma | 4.17.5-103.el9_2.alma | Jul 20, 2023 | A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not enforced if an admin configured "server signing = required" or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. This flaw allows an attacker to per | |
| CVE-2023-34968 | Med | 5.3 | < 4.18.6-100.el9 | 4.18.6-100.el9 | Jul 20, 2023 | A path disclosure vulnerability was found in Samba. As part of the Spotlight protocol, Samba discloses the server-side absolute path of shares, files, and directories in the results for search queries. This flaw allows a malicious client or an attacker with a targeted RPC request | |
| CVE-2023-34967 | Med | 5.3 | < 4.18.6-100.el9 | 4.18.6-100.el9 | Jul 20, 2023 | A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight.

| CVE-2023-34966 | Hig | 7.5 | < 4.18.6-100.el9 | 4.18.6-100.el9 | Jul 20, 2023 | An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not validate a field in the network packet that contains the count of elements | |
| CVE-2022-2127 | Med | 5.9 | < 4.18.6-100.el9 | 4.18.6-100.el9 | Jul 20, 2023 | An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to | |
| CVE-2022-38023 | Hig | 8.1 | < 4.16.4-4.el8_7 | 4.16.4-4.el8_7 | Nov 9, 2022 | Netlogon RPC Elevation of Privilege Vulnerability | |

Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control | |
| CVE-2021-20316 | Med | 6.8 | < 4.15.5-8.el8_6 | 4.15.5-8.el8_6 | Aug 23, 2022 | A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share. | |
| CVE-2021-23192 | Hig | 7.5 | < 4.14.5-7.el8_5 | 4.14.5-7.el8_5 | Mar 2, 2022 | A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements. | |
| CVE-2021-44141 | Med | 4.3 | < 4.15.5-8.el8_6 | 4.15.5-8.el8_6 | Feb 21, 2022 | All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this |
