CVE-2018-5995

Published: 7 August 2018

The pcpu_embed_first_chunk function in mm/percpu.c in the Linux kernel through 4.14.14 allows local users to obtain sensitive address information by reading dmesg data from a "pages/cpu" printk call.

From the Ubuntu Security Team

It was discovered that the per cpu memory allocator in the Linux kernel could report kernel pointers via dmesg. An attacker could use this to expose sensitive information or in conjunction with another kernel vulnerability.

Priority

Negligible

CVSS 3 base score: 5.5
