CVSS: 8.2EPSS: 0%CPEs: 9EXPL: 1CVE-2023-2008 – Linux Kernel udmabuf Improper Validation of Array Index Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-2008
A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault handler. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. A flaw was found in the Linux kernel's udmabuf device driver, within a fault handler. • https://github.com/bluefrostsecurity/CVE-2023-2008 https://bugzilla.redhat.com/show_bug.cgi?id=2186862 https://github.com/torvalds/linux/commit/05b252cccb2e5c3f56119d25de684b4f810ba4 https://security.netapp.com/advisory/ntap-20230517-0007 https://www.zerodayinitiative.com/advisories/ZDI-23-441 https://access.redhat.com/security/cve/CVE-2023-2008 • CWE-129: Improper Validation of Array Index •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2023-2007 – Linux Kernel DPT I2O Controller Time-Of-Check Time-Of-Use Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2023-2007
The specific flaw exists within the DPT I2O Controller driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel. This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability.

https://notcve.org/view.php?id=CVE-2023-2019
A flaw was found in the Linux kernel's netdevsim device driver, within the scheduling of events. This issue results from the improper management of a reference count. This may allow an attacker to create a denial of service condition on the system. This vulnerability allows local attackers to create a denial-of-service condition on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability.

https://notcve.org/view.php?id=CVE-2023-2006
A race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC bundles. This issue results from the lack of proper locking when performing operations on an object. This may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2023-1872 – Use-after-free in Linux kernel's io_uring subsystem
https://notcve.org/view.php?id=CVE-2023-1872
A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local privilege escalation. The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered.
