kernel: smb: client: fix query directory 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 client attempts to free the same memory buffer twice during a directory query operation. An attacker could potentially exploit this flaw to cause memory corruption,...

CVE-2026-89632

A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server could exploit this vulnerability by sending specially crafted data, leading to an out-of-bounds read. This occurs because the reparsebufptr function reads data before properly validating the buffer size,...

CVE-2026-89637

A flaw was found in the Linux kernel's Server Message Block SMB client. When processing a malformed secondary TRANSACT2 response, a use-after-free UAF vulnerability and a buffer leak can occur in the cifschecktrans2 function. This can lead to a dangling buffer being reused by the demux thread,...

CVE-2026-89636

A flaw was found in the Linux kernel's Server Message Block SMB client. When the freetgts function frees data structures, a pointer ce-tgthint is not properly reset, leaving it pointing to a memory location that has already been deallocated. If this pointer is subsequently used, it can lead to a...

CVE-2026-89633

A flaw was found in the Linux kernel's Server Message Block SMB client. The coalescet2 function processes server-supplied DataOffset fields without proper validation against buffer boundaries. A remote attacker could exploit this by crafting malicious SMB responses. This could lead to out-of-boun...

CVE-2026-89630

A flaw was found in the Linux kernel's Server Message Block SMB client. An incorrect calculation of the dataoffset bound in the isvalidoplockbreak function can lead to a read overflow. This vulnerability allows a malicious SMB server to potentially trigger an out-of-bounds read, which could resul...

CVE-2026-89634

A flaw was found in the Server Message Block SMB client within the Linux kernel. An integer overflow in the ALIGN function, specifically within the symlinkdata error context loop, can lead to an out-of-bounds read. This issue allows a malicious SMB server to cause a denial of service DoS by...
