Linux: Exposure of Resource to Wrong Sphere

Published Updated By the CyberSecBulletin desk

CVE-2024-36033 is a high-severity exposure of resource to wrong sphere 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 a3dff121a7f5104c4c2d47edaa2351837ef645dd, bcccdc947d2ca5972b1e92d0dea10803ddc08ceb, ba307abed5e09759845c735ba036f8c12f55b209 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 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.
