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 •

A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system crash or other undefined behaviors.

A use-after-free flaw was found in xen_9pfs_front_removet in net/9p/trans_xen.c in Xen transport for 9pfs in the Linux Kernel. This flaw could allow a local attacker to crash the system due to a race problem, possibly leading to a kernel information leak. • https://lore.kernel.org/all/20230313090002.3308025-1-zyytlz.wz%40163.com • CWE-416: Use After Free •

An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order for an attacker to exploit this, the system must have netrom routing configured or the attacker must have the CAP_NET_ADMIN capability. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.11 https://github.com/torvalds/linux/commit/611792920925fb088ddccbe2783c7f92fdfb6b64 • CWE-416: Use After Free •
CVSS: 8.2EPSS: 0%CPEs: 7EXPL: 0CVE-2023-31436 – Linux Kernel Net Scheduler Out-Of-Bounds Access Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-31436
qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX. An out-of-bounds memory access flaw was found in the Linux kernel’s traffic control (QoS) subsystem in how a user triggers the qfq_change_class function with an incorrect MTU value of the network device used as lmax. This flaw allows a local user to crash or potentially escalate their privileges on the system. This vulnerability allows local attackers to escalate privileges on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of the MTU value provided to the QFQ Scheduler. • http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.13 https://github.com/torvalds/linux/commit/3037933448f60f9acb705997eae62013ecb81e0d https://lists.debian.org/debian-lts-announce/2023/06/msg00008.html https://security • CWE-787: Out-of-bounds Write •
