Linux: Exposure of Resource to Wrong Sphere

Published Updated By the CyberSecBulletin desk

CVE-2024-36032 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 62d5550ab62042dcceaf18844d0feadbb962cffe, 57062aa13e87b1a78a4a8f6cb5fab6ba24f5f488, 6b63e0ef4d3ce0080395e5091fba2023f246c45a 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 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.
