Severity ?

3.3 (Low) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: avoid kernel-infoleak from struct iw_point struct iw_point has a 32bit hole on 64bit arches. struct iw_point { void __user *pointer; /* Pointer to the data (in user space) */ __u16 length; /* number of fields or size in bytes */ __u16 flags; /* Optional params */ }; Make sure to zero the structure to avoid disclosing 32bits of kernel data to user space.
