openSUSE Tumbleweed: Out-of-bounds Read
CVE-2023-32190 is a high-severity out-of-bounds read vulnerability in openSUSE Tumbleweed from SUSE, with a CVSS 4.0 base score of 8.5 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 version 0.26-37.1 as the first without the flaw, so updating openSUSE Tumbleweed to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.2% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
