NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-devel package and not the kernel-debug-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The stack randomization feature in the Linux kernel before 3.19.1 on 64-bit platforms uses incorrect data types for the results of bitwise left-shift operations, which makes it easier for attackers to bypass the ASLR protection mechanism by predicting the address of the top of the stack, related to the randomize_stack_top function in fs/binfmt_elf.c and the stack_maxrandom_size function in arch/x86/mm/mmap.c.
