CVE-2023-22024
https://notcve.org/view.php?id=CVE-2023-22024
In the Unbreakable Enterprise Kernel (UEK), the RDS module in UEK has two setsockopt(2) options, RDS_CONN_RESET and RDS6_CONN_RESET, that are not re-entrant. A malicious local user with CAP_NET_ADMIN can use this to crash the kernel. CVSS 3.1 Base Score 5.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

CVE-2023-3161 – kernel: fbcon: shift-out-of-bounds in fbcon_set_font()
https://notcve.org/view.php?id=CVE-2023-3161
A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds occurs leading to undefined behavior and possible denial of service.

https://notcve.org/view.php?id=CVE-2023-1652
A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem. • https://access.redhat.com/security/cve/cve-2023-1652 https://security.netapp.com/advisory/ntap-20230511-0006 https://access.redhat.com/security/cve/CVE-2023-1652 https://bugzilla.redhat.com/show_bug.cgi?id=2182031 • CWE-416: Use After Free •
CVE-2022-21499 – kernel: possible to use the debugger to write zero into a location of choice
https://notcve.org/view.php?id=CVE-2022-21499
KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). KGDB y KDB permiten el acceso de lectura y escritura a la memoria del kernel, y por lo tanto deben ser restringidos durante el bloqueo. • http://packetstormsecurity.com/files/168191/Kernel-Live-Patch-Security-Notice-LSN-0089-1.html https://git.kernel.org/linus/eadb2f47a3ced5c64b23b90fd2a3463f63726066 https://www.debian.org/security/2022/dsa-5161 https://access.redhat.com/security/cve/CVE-2022-21499 https://bugzilla.redhat.com/show_bug.cgi?id=2084183 • CWE-787: Out-of-bounds Write •
