https://notcve.org/view.php?id=CVE-2023-37453
An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds and crash in read_descriptors in drivers/usb/core/sysfs.c. An out-of-bounds read issue was found in the USB subsystem in the Linux kernel. This flaw allows a malicious user to crash the system, resulting in a denial of service condition. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1e4c574225cc5a0553115e5eb5787d1474db5b0f https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=85d07c55621676d47d873d2749b88f783cd4d5a1 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=de28e469da75359a2bb8cd8778b78aa64b1be1f4 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ff33299ec8bb80cdcc073ad9c506bd79bb2ed20b https://lore.kernel.org/all/000000000000c0ffe505fe86c9ca%40google.com/T htt • CWE-125: Out-of-bounds Read •
CVSS: 7.8EPSS: 0%CPEs: 15EXPL: 2CVE-2023-35001 – Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability
https://notcve.org/view.php?id=CVE-2023-35001
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace Vulnerabilidad de Lectura/Escritura en nftables Fuera de los Límites del kernel de Linux; nft_byteorder administra incorrectamente los contenidos de registro de VM cuando CAP_NET_ADMIN está en cualquier espacio de nombres de usuario o red An out-of-bounds (OOB) memory access flaw was found in the Netfilter module in the Linux kernel's nft_byteorder_eval in net/netfilter/nft_byteorder.c. A bound check failure allows a local attacker with CAP_NET_ADMIN access to cause a local privilege escalation issue due to incorrect data alignment. 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. The specific flaw exists within the processing of nft chains. The issue results from incorrect pointer scaling, which can result in a memory access past the end of an array. • https://github.com/synacktiv/CVE-2023-35001 https://github.com/syedhafiz1234/nftables-oob-read-write-exploit-CVE-2023-35001- http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html http://www.openwall.com/lists/oss-security/2023/07/05/3 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.debian.org/debian-lts-announce/2024/01/m • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-31248
Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()` failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace Vulnerabilidad de Escalada de Privilegios Locales de Use-After-Free de Linux nftables; 'nft_chain_lookup_byid()' no pudo comprobar si una cadena estaba activa y CAP_NET_ADMIN está en cualquier espacio de nombres de usuario o red A use-after-free flaw was found in the Linux kernel's Netfilter module in net/netfilter/nf_tables_api.c in nft_chain_lookup_byid. This flaw allows a local attacker to cause a local privilege escalation issue due to a missing cleanup. 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. The specific flaw exists within the handling of nft_chains. The issue results from the lack of validating the status of a chain while processing lookup on the chain. • http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html http://www.openwall.com/lists/oss-security/2023/07/05/2 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/RGZC5XOANA75OJ4XARBBXYSLDKUIJI5E https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.or • CWE-416: Use After Free •
