https://notcve.org/view.php?id=CVE-2023-34256
An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against attackers with the stated "When modifying the block device while it is mounted by the filesystem" access. Se ha descubierto un problema en el kernel de Linux en las versiones anteriores a 6.3.3. Hay una lectura fuera de límites en crc16 en "lib/crc16.c" cuando se llama dese "fs/ext4/super.c" porque "ext4_group_desc_csum" no comprueba correctamente un desplazamiento. • https://bugzilla.suse.com/show_bug.cgi?id=1211895 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4f04351888a83e595571de672e0a4a8b74f4fb31 https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://syzkaller.appspot.com/bug?extid=8785e41224a3afd04321 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2023-2002
A vulnerability was found in the HCI sockets implementation due to a missing capability check in net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of management commands, compromising the confidentiality, integrity, and availability of Bluetooth communication. • https://github.com/lrh2000/CVE-2023-2002 https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://security.netapp.com/advisory/ntap-20240202-0004 https://www.debian.org/security/2023/dsa-5480 https://www.openwall.com/lists/oss-security/2023/04/16/3 https://access.redhat.com/security/cve/CVE-2023-2002 https://bugzilla.redhat.com/show_bug.cgi?id=2187308 • CWE-250: Execution with Unnecessary Privileges CWE-863: Incorrect Authorization •
CVSS: 8.1EPSS: 0%CPEs: 8EXPL: 0CVE-2023-32257 – Session race condition remote code execution vulnerability
https://notcve.org/view.php?id=CVE-2023-32257
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_SESSION_SETUP and SMB2_LOGOFF commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.
