CVE-2023-34256
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 •
CVE-2023-22651
https://notcve.org/view.php?id=CVE-2023-22651
Improper Privilege Management vulnerability in SUSE Rancher allows Privilege Escalation. A failure in the update logic of Rancher's admission Webhook may lead to the misconfiguration of the Webhook. This component enforces validation rules and security checks before resources are admitted into the Kubernetes cluster. The issue only affects users that upgrade from 2.6.x or 2.7.x to 2.7.2. Users that did a fresh install of 2.7.2 (and did not follow an upgrade path) are not affected. • https://bugzilla.suse.com/show_bug.cgi?id=CVE-2023-22651 https://github.com/rancher/rancher/security/advisories/GHSA-6m9f-pj6w-w87g • CWE-269: Improper Privilege Management •
CVE-2023-29552 – Service Location Protocol (SLP) Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2023-29552
The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-service attack with a significant amplification factor. The Service Location Protocol (SLP) contains a denial-of-service (DoS) vulnerability that could allow an unauthenticated, remote attacker to register services and use spoofed UDP traffic to conduct a denial-of-service (DoS) attack with a significant amplification factor. • https://blogs.vmware.com/security/2023/04/vmware-response-to-cve-2023-29552-reflective-denial-of-service-dos-amplification-vulnerability-in-slp.html https://curesec.com/blog/article/CVE-2023-29552-Service-Location-Protocol-Denial-of-Service-Amplification-Attack-212.html https://datatracker.ietf.org/doc/html/rfc2608 https://github.com/curesec/slpload https://security.netapp.com/advisory/ntap-20230426-0001 https://www.bitsight.com/blog/new-high-severity-vulnerability-cve-2023-29552-discovered-service-location-protoco •

CVE-2023-23005
https://notcve.org/view.php?id=CVE-2023-23005
In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached. • https://bugzilla.suse.com/show_bug.cgi?id=1208844#c2 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2 https://github.com/torvalds/linux/commit/4a625ceee8a0ab0273534cb6b432ce6b331db5ee • CWE-476: NULL Pointer Dereference •
