CVE-2026-62960 Git for Windows: Server-advertised bundle-uri can trigger outbound SMB callbacks via UNC and file:// paths on Windows

Git for Windows is the Windows port of Git. Prior to 2.55.0.windows.4, a malicious remote Git server can advertise a bundle URI that reaches transportgetremotebundleuri, fetchbundleuriinternal, and copyuritofile in bundle-uri.c during clone or fetch when transfer.bundleuri=true. Non-HTTPS values...

CVE-2026-62960

Git for Windows prior to 2.55.0.windows.4 is vulnerable to a security bypass in bundle-uri.c . When transfer.bundleuri=true, a malicious remote Git server can advertise a bundle URI processed by transport_get_remote_bundle_uri(), fetch_bundle_uri_internal(), and copy_uri_to_file(). Non-HTTP(S) va...

kernel: smb: client: validate DFS referral PathConsumed

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker could send a specially crafted SMB response containing a malformed Distributed File System DFS referral. This could cause the PathConsumed value to exceed the search name length, leading to an out-of-bounds...

kernel: smb: client: fix query_info() replay double-free

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the queryinfo replay mechanism attempts to free a response buffer that has already been released. This can happen if an error occurs during the initialization of an SMB2...

kernel: smb/client: handle overlapping allocated ranges in fallocate

A flaw was found in the Linux kernel's Server Message Block SMB client. The smb3simplefallocaterange function, which manages file allocation, can incorrectly process overlapping allocated ranges provided by a server. This can result in parts of a file not being properly zero-filled, leading to...

kernel: smb: client: mask server-provided mode to 07777 in modefromsid

A flaw was found in the Linux kernel's Server Message Block SMB client. When processing server-provided file mode information, the system incorrectly applies these modes without proper security masking. This can result in unintended file permissions, potentially allowing unauthorized access to...

kernel: smb/client: handle overlapping allocated ranges in fallocate

A flaw was found in the Linux kernel's Server Message Block SMB client. The smb3simplefallocaterange function, which manages file allocation, can incorrectly process overlapping allocated ranges provided by a server. This can result in parts of a file not being properly zero-filled, leading to...

kernel: smb/client: fix out-of-bounds read in symlink_data()

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability arises from insufficient length validation in the smb2checkmessage function when processing symlink error responses. A remote attacker could exploit this by sending a specially crafted symlink error respons...

kernel: smb: client: fix double-free in SMB2_open() replay

A flaw was found in the Linux kernel's Server Message Block SMB client. A double-free vulnerability exists in the SMB2open replay mechanism. This occurs when a response-bearing attempt returns a replayable error and frees its response buffer, and then the cleanup process attempts to free the same...
