CVE-2023-42754 – Kernel: ipv4: null pointer dereference in ipv4_send_dest_unreach()
https://notcve.org/view.php?id=CVE-2023-42754
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system. Se encontró una falla de desreferencia del puntero NULL en la pila ipv4 del kernel de Linux. Se suponía que el búfer de socket (skb) estaba asociado con un dispositivo antes de llamar a __ip_options_compile, lo que no siempre es el caso si ipvs redirige el skb. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-42754 https://bugzilla.redhat.com/show_bug.cgi?id=2239845 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH https://lists.fedoraproject.org/archives/list/package-announc • CWE-476: NULL Pointer Dereference •
CVE-2023-42756 – Kernel: netfilter: race condition between ipset_cmd_add and ipset_cmd_swap
https://notcve.org/view.php?id=CVE-2023-42756
A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`. This issue may allow a local user to crash the system. Se encontró una falla en el subsistema Netfilter del kernel de Linux. Una condición de ejecución entre IPSET_CMD_ADD e IPSET_CMD_SWAP puede provocar un panic en el kernel debido a la invocación de `__ip_set_put` en un `set` incorrecto. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/security/cve/CVE-2023-42756 https://bugzilla.redhat.com/show_bug.cgi?id=2239848 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GPMICQ2HVZO5UAM5KPXHAZKA2U3ZDOO6 https://lists.fedoraproject.org/archives/list/package& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2023-4156 – Heap out of bound read in builtin.c
https://notcve.org/view.php?id=CVE-2023-4156
A heap out-of-bounds read flaw was found in builtin.c in the gawk package. This issue may lead to a crash and could be used to read sensitive information. Se encontró un error de lectura fuera de límites en el paquete gawk de buildin.c. Este problema puede provocar un bloqueo y podría utilizarse para leer información confidencial. • https://access.redhat.com/security/cve/CVE-2023-4156 https://bugzilla.redhat.com/show_bug.cgi?id=2215930 • CWE-125: Out-of-bounds Read •
CVE-2023-4387 – Kernel: vmxnet3: use-after-free in vmxnet3_rq_alloc_rx_buf()
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 •
CVE-2022-40982 – hw: Intel: Gather Data Sampling (GDS) side channel vulnerability
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 •
