Severity

3.3 (Low) CVSS_V3 - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N CVSS Calculator

Summary

[none]

Details

On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LDPREFERMAP32BITEXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
