drivers/net/ieee802154/atusb.c in the Linux kernel 4.9.x before 4.9.6 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging use of more than one virtual page for a DMA scatterlist.

Security readout for executives and security teams

This is a Linux kernel flaw affecting 4.9.x kernels before 4.9.6. A local user may crash the system or corrupt memory through an IEEE 802.15.4 USB driver interaction with CONFIG_VMAP_STACK. Business impact is mainly host availability risk on exposed multi-user systems. Exposure appears limited to Linux 4.9.x systems before 4.9.6 where CONFIG_VMAP_STACK and the atusb IEEE 802.15.4 USB driver are relevant. Risk is higher on systems allowing untrusted local users or workloads. Treat as a targeted availability and stability issue, not an internet-wide emergency. Patch during the next appropriate kernel maintenance window, faster for shared servers, lab systems, or hosts with untrusted local users. Mitigation focus: Upgrade affected Linux 4.9.x kernels to 4.9.6 or a vendor-patched kernel.; Apply distribution security updates that include the upstream atusb driver fix.; Prioritize multi-user systems and hosts running untrusted local workloads..
