Description

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.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

4.7 ≤ v < 4.9.5
Affected range stops below 4.9.5, so it looks safe — our inference, not a vendor statement
