CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-38409 – kernel: fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment
https://notcve.org/view.php?id=CVE-2023-38409
An issue was discovered in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Linux kernel before 6.2.12. Because an assignment occurs only for the first vc, the fbcon_registered_fb and fbcon_display arrays can be desynchronized in fbcon_mode_deleted (the con2fb_map points at the old fb_info). A memory corruption flaw was found in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Framebuffer Console in the Linux kernel. This flaw allows a local attacker to crash the system, leading to a denial of service. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.12 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=fffb0b52d5258554c645c966c6cbef7de50b851d https://access.redhat.com/security/cve/CVE-2023-38409 https://bugzilla.redhat.com/show_bug.cgi?id=2230042 • CWE-129: Improper Validation of Array Index CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

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 •
