CVE-2026-46185

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.
