Description
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.
Ubuntu-Description
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.
