CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 5CVE-2023-32233 – kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation
https://notcve.org/view.php?id=CVE-2023-32233
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled. A use-after-free vulnerability was found in the Netfilter subsystem of the Linux kernel when processing batch requests to update nf_tables configuration. This vulnerability can be abused to perform arbitrary reads and writes in kernel memory. • https://github.com/oferchen/POC-CVE-2023-32233 https://github.com/PIDAN-HEIDASHUAI/CVE-2023-32233 https://github.com/Liuk3r/CVE-2023-32233 https://github.com/RogelioPumajulca/TEST-CVE-2023-32233 https://github.com/void0red/CVE-2023-32233 http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html http://www.openwall.com/lists/oss-security/2023/05/15/5 https://bugzilla.redhat.com/show_bug.cgi?id=2196105 https://git.kernel.org/cgit/linux/k • CWE-416: Use After Free •
CVSS: 7.5EPSS: 2%CPEs: 8EXPL: 0CVE-2023-2156 – Linux Kernel IPv6 RPL Protocol Reachable Assertion Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2023-2156
A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the RPL protocol. • http://www.openwall.com/lists/oss-security/2023/05/17/8 http://www.openwall.com/lists/oss-security/2023/05/17/9 http://www.openwall.com/lists/oss-security/2023/05/18/1 http://www.openwall.com/lists/oss-security/2023/05/19/1 https://bugzilla.redhat.com/show_bug.cgi?id=2196292 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://security.netapp.com/advisory/ntap-20230622-0001 https://www.debian.org/security/2023/dsa-5448 https:// • CWE-617: Reachable Assertion •
