kernel: smb: client: fix OOB reads parsing symlink error response

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote, untrusted server could send a specially crafted symlink error response, leading to an out-of-bounds read vulnerability. This could result in the disclosure of sensitive information from the kernel's memory to a loca...

CVE-2026-98170

A flaw was found in the Linux kernel's SMB client. When processing extended file attributes returned by a server, insufficient buffer validation allows the kernel to read data past the allocated boundaries. A malicious or compromised server could exploit this issue by returning a malformed...

CVE-2026-98167

A flaw was found in the Linux kernel's SMB client. When processing compound encrypted Protocol Data Units PDUs, the client incorrectly validates the length of individual messages within the compound frame. A malicious or compromised SMB server can exploit this flaw by returning truncated sub-PDUs...

CVE-2026-98168

A flaw was found in the Linux kernel's Server Message Block SMB client. In the reparse point query handling logic, the client fails to properly validate response buffer boundaries before accessing data structures. A malicious or compromised SMB server can exploit this by returning a crafted...

CVE-2026-98169

A flaw was found in the Linux kernel's Server Message Block SMB client. This issue leads to information disclosure caused by an out-of-bounds memory read during snapshot enumeration. A malicious SMB server can provide an unexpectedly short response, causing the kernel client to read beyond the...
