Vulnerability from github – Published: 2024-09-27 15:30 – Updated: 2025-11-04 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ELF: fix kernel.randomize_va_space double read

ELF loader uses "randomize_va_space" twice. It is sysctl and can change at any moment, so 2 loads could see 2 different values in theory with unpredictable consequences.

Issue exactly one load for consistent value across one exec.

Severity

5.5 (Medium)
