https://notcve.org/view.php?id=CVE-2023-3223
A flaw was found in undertow. Servlets annotated with @MultipartConfig may cause an OutOfMemoryError due to large multipart content. This may allow unauthorized users to cause remote Denial of Service (DoS) attack. If the server uses fileSizeThreshold to limit the file size, it's possible to bypass the limit by setting the file name in the request to null.

CVE-2023-4194 – Kernel: tap: tap_open(): correctly initialize socket uid next fix of i_uid to current_fsuid
https://notcve.org/view.php?id=CVE-2023-4194
A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 ("tun: tun_chr_open(): correctly initialize socket uid"), - 66b2c338adce ("tap: tap_open(): correctly initialize socket uid"), pass "inode->i_uid" to sock_init_data_uid() as the last parameter and that turns out to not be accurate. Se ha encontrado un fallo en la funcionalidad TUN/TAP del kernel de Linux. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/security/cve/CVE-2023-4194 https://bugzilla.redhat.com/show_bug.cgi?id=2229498 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/344H6HO6SSC4KT7PDFXSDIXKMKHISSGF https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3TYLSJ2SAI7RF56ZLQ5CQWCJLVJSD73Q https://lore.kernel.org/all/20230731164237.48365-1 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-863: Incorrect Authorization •
