EPSS Score14.7%

EPSS (Exploit Prediction Scoring System) estimates a 14.7% chance this CVE is exploited in the wild within the next 30 days — higher than 97% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

Linux Kernel contains an integer overflow vulnerability in the create_elf_tables() function which could allow an unprivileged local user with access to SUID (or otherwise privileged) binary to escalate their privileges on the system.

Required Action
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Description

An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable.
