Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to the
iw point structure within the Wi-Fi subsystem. The iw point structure contains a 32-bit hole on 64-bit architectures. This can lead to the disclosure of 32 bits of kernel data to user space. The issue arises because the structure is not properly zeroed, potentially exposing sensitive kernel information. The structure iw point includes the following members: pointer (a pointer to data in user space), length (the number of fields or size in bytes), and flags (optional parameters).Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
