CVE-2026-46185
CVSS v3.1
9.1
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An out-of-bounds read exists in the
symlink data() function. This occurs because smb2 check message() returns success without validating the length for the symlink error response. Consequently, iov->iov len may be smaller than the size of struct smb2 err rsp. If the buffer contains only the base SMB2 header, accessing err->ErrorContextCount or err->ByteCount results in an out-of-bounds read, which is a memory access error where the system reads data outside the intended buffer boundaries.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
