https://notcve.org/view.php?id=CVE-2023-4569
A memory leak flaw was found in nft_set_catchall_flush in net/netfilter/nf_tables_api.c in the Linux Kernel. This issue may allow a local attacker to cause double-deactivations of catchall elements, which can result in a memory leak. • https://access.redhat.com/security/cve/CVE-2023-4569 https://bugzilla.redhat.com/show_bug.cgi?id=2235470 https://patchwork.ozlabs.org/project/netfilter-devel/patch/20230812110526.49808-1-fw@strlen.de https://www.debian.org/security/2023/dsa-5492 • CWE-401: Missing Release of Memory after Effective Lifetime CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') •

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 •
CVSS: 6.7EPSS: 0%CPEs: 18EXPL: 1CVE-2023-4273 – Kernel: exfat: stack overflow in exfat_get_uniname_from_ext_entry
https://notcve.org/view.php?id=CVE-2023-4273
A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack. Se ha encontrado un fallo en el controlador exFAT del núcleo de Linux. La vulnerabilidad se encuentra en la implementación de la función de reconstrucción de nombres de archivo, que se encarga de leer entradas de nombres de archivo de un índice de directorio y fusionar partes de nombres de archivo pertenecientes a un archivo en un único nombre de archivo largo. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/security/cve/CVE-2023-4273 https://bugzilla.redhat.com/show_bug.cgi?id=2221609 https://dfir.ru/2023/08/23/cve-2023-4273-a-vulnerability-in-the-linux-exfat-driver 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.fedorapr • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

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.
