https://notcve.org/view.php?id=CVE-2023-4387
A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a kernel information leak problem. Se encontró una falla de use-after-free en vmxnet3_rq_alloc_rx_buf en drivers/net/vmxnet3/vmxnet3_drv.c en el controlador NIC Ethernet vmxnet3 de VMware en el kernel de Linux. Este problema podría permitir que un atacante local bloquee el sistema debido a una doble liberación mientras se limpia vmxnet3_rq_cleanup_all, lo que también podría provocar un problema de fuga de información del kernel. • https://access.redhat.com/security/cve/CVE-2023-4387 https://bugzilla.redhat.com/show_bug.cgi?id=2219270 https://github.com/torvalds/linux/commit/9e7fef9521e73ca8afd7da9e58c14654b02dfad8 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2022-40982
Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. La exposición de información a través del estado microarquitectónico tras la ejecución transitoria en determinadas unidades de ejecución vectorial de algunos procesadores Intel(R) puede permitir a un usuario autenticado la divulgación potencial de información a través del acceso local. A Gather Data Sampling (GDS) transient execution side-channel vulnerability was found affecting certain Intel processors. This issue may allow a local attacker using gather instruction (load from memory) to infer stale data from previously used vector registers on the same physical core. • http://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00828.html https://access.redhat.com/solutions/7027704 https://aws.amazon.com/security/security-bulletins/AWS-2023-007 https://downfall.page https://lists.debian.org/debian-lts-announce/2023/08/msg00013.html https://lists.debian.org/debian-lts-announce/2023/08/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/HKKYIK2EASDNUV4I7EFJKNBVO3KCKGRR https://lists.fedoraproject.org • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy CWE-1342: Information Exposure through Microarchitectural State after Transient Execution •

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.

A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate requests. An authenticated attacker who could obtain information from a user request within the same realm could use that data to impersonate the victim and generate new session tokens. This issue could impact confidentiality, integrity, and availability.

CVSS: 5.9EPSS: 0%CPEs: 10EXPL: 0CVE-2022-2127 – Samba: out-of-bounds read in winbind auth_crap
https://notcve.org/view.php?id=CVE-2022-2127
An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can trigger an out-of-bounds read in Winbind, possibly resulting in a crash. • https://access.redhat.com/errata/RHSA-2023:6667 https://access.redhat.com/errata/RHSA-2023:7139 https://access.redhat.com/errata/RHSA-2024:0423 https://access.redhat.com/errata/RHSA-2024:0580 https://access.redhat.com/security/cve/CVE-2022-2127 https://bugzilla.redhat.com/show_bug.cgi?id=2222791 https://lists.debian.org/debian-lts-announce/2024/04/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPCSGND7LO467AJGR5DYBGZLTCGTOBCC https:& • CWE-125: Out-of-bounds Read •
