kernel: proc: protect mm start_code/end_code in /proc/pid/stat
Published Jul 18, 2011
CVSS 2.0 · 2.1 Low
EPSS < 1%
KEV · Not listed
Description
The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary.
