CVE-2023-7258 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. A denial of service exists in Gvisor Sandbox where a bug in reference counting code in mount point tracking could lead to a panic, making it possible for an attacker running as root and with permission to mount volumes to kill the sandbox. We recommend upgrading past commit 6a112c60a257dadac59962e0bc9e9b5aee70b5b6. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
