Linux: Out-of-bounds Read

Published Updated By the CyberSecBulletin desk

CVE-2024-58014 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 0a457223cb2b9ca46bae7de387d0f4c093b0220d, 13ef16c4fe384b1e70277bbe1d87934ee6c81e12, d280a12e9b87819a8a209639d600b48a2d6d65dc as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

The underlying weakness: Out-of-bounds Read

The product reads data past the end, or before the beginning, of the intended buffer.

How developers prevent this class of flaw

  • Use a language that provides appropriate memory abstractions.
