CVE-2023-1998 is a moderate-severity vulnerability affecting the Linux kernel, specifically when userspace processes enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL
and using seccomp. This issue can potentially expose systems to attacks, even after enabling certain mitigations. The vulnerability impacts Linux-based systems running the Linux kernel and Debian Linux, with x86 CPUs supporting IBRS but not eIBRS.
How do I know if I'm affected?
To determine if you're affected by the vulnerability, check if your system is running the Linux kernel up to version 6.3 or Debian Linux version 10.0, particularly on x86 CPUs supporting IBRS but not eIBRS. This issue can expose your system to attacks even after enabling certain mitigations. If your system matches these criteria, it may be vulnerable to this moderate-severity issue, which could potentially leak sensitive information from user-space applications.
What should I do if I'm affected?
If you're affected by the vulnerability, update your Linux kernel to version 6.3 or later, or upgrade your Debian Linux 10.0 system's linux-5.10 packages to version 5.10.178-3~deb10u1. Regularly check for updates and monitor security advisories to maintain system security.
Is CVE-2023-1998 in CISA’s Known Exploited Vulnerabilities Catalog?
The CVE-2023-1998 vulnerability is not listed in CISA's Known Exploited Vulnerabilities Catalog. This issue, related to the Linux kernel and userspace processes enabling mitigations, has a medium severity rating of 5.6. It is important to update your Linux kernel to version 6.3 or later, or upgrade your Debian Linux 10.0 system's linux-5.10 packages to version 5.10.178-3~deb10u1 to address this vulnerability.
Weakness enumeration
The weakness enumeration for this vulnerability is categorized as CWE-203 and CWE-1303, which highlights two identified weaknesses in the Linux kernel, related to observable discrepancy and non-transparent sharing of microarchitectural resources, which can lead to potential security issues.
For more details
CVE-2023-1998 is a moderate-severity vulnerability affecting the Linux kernel and Debian Linux systems. After analyzing the details provided by the National Vulnerability Database, Google Security Research, and Debian mailing list advisories, it is crucial to update your system to mitigate potential attacks.
