SUSE CVE-2026-89632

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix use-before-check of ReparseDataLength in reparsebufptr reparsebufptr reads buf-ReparseDataLength before checking that count covers the full fixed header: buf = struct reparsedatabuffer u8 io + off; len = sizeofbu...

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-2026-89632

CVE-2026-89632 is an out-of-bounds read in the Linux kernel's SMB client , specifically in the reparse_buf_ptr() function. The root cause is a use-before-check of ReparseDataLength (offset 4, 2 bytes): the value is read before verifying that the received buffer length (count) is at least the full...
