Vulnerability from fkie_nvd - Published: 2017-02-06 06:59 - Updated: 2026-06-17 01:20
Summary
The freelist-randomization feature in mm/slab.c in the Linux kernel 4.8.x and 4.9.x before 4.9.5 allows local users to cause a denial of service (duplicate freelist entries and system crash) or possibly have unspecified other impact in opportunistic circumstances by leveraging the selection of a large value for a random number.
