CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2022-48619 – kernel: event code falling outside of a bitmap in input_set_capability() leads to panic
https://notcve.org/view.php?id=CVE-2022-48619
An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause a denial of service (panic) because input_set_capability mishandles the situation in which an event code falls outside of a bitmap. Se descubrió un problema en drivers/input/input.c en el kernel de Linux anterior a la versión 5.17.10. Un atacante puede provocar una denegación de servicio (pánico) porque input_set_capability maneja mal la situación en la que un código de evento queda fuera de un mapa de bits. A vulnerability was found in drivers/input/input.c in the Linux Kernel, where the input_set_capability() function mishandles scenarios where an event code is outside the bitmap. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.17.10 https://github.com/torvalds/linux/commit/409353cbe9fe48f6bc196114c442b1cff05a39bc https://access.redhat.com/security/cve/CVE-2022-48619 https://bugzilla.redhat.com/show_bug.cgi?id=2258012 • CWE-400: Uncontrolled Resource Consumption CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2024-0340
A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file. Se encontró una vulnerabilidad en vhost_new_msg en drivers/vhost/vhost.c en el kernel de Linux, que no inicializa correctamente la memoria en los mensajes pasados entre los invitados virtuales y el sistema operativo host en la función vhost/vhost.c:vhost_new_msg(). Este problema puede permitir a los usuarios locales privilegiados leer algunos contenidos de la memoria del kernel cuando leen desde el archivo del dispositivo /dev/vhost-net. • https://access.redhat.com/errata/RHSA-2024:3618 https://access.redhat.com/errata/RHSA-2024:3627 https://access.redhat.com/security/cve/CVE-2024-0340 https://bugzilla.redhat.com/show_bug.cgi?id=2257406 https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html https://lore.kernel.org/lkml/5kn47peabxjrptkqa6dwtyus35ahf4pcj4qm4pumse33kxqpjw@mec4se5relrc/T • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of service (DoS) attack due to a refcount overflow. Se encontró un problema de pérdida de memoria en ctnetlink_create_conntrack en net/netfilter/nf_conntrack_netlink.c en el kernel de Linux.

CVSS: 8.8EPSS: 0%CPEs: 10EXPL: 0CVE-2023-6546 – Kernel: gsm multiplexing race condition leads to privilege escalation
https://notcve.org/view.php?id=CVE-2023-6546
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system. Se encontró una condición de ejecución en el multiplexor tty GSM 0710 en el kernel de Linux. Este problema ocurre cuando dos subprocesos ejecutan GSMIOC_SETCONF ioctl en el mismo descriptor de archivo tty con la disciplina de línea gsm habilitada y puede provocar un problema de use after free en una estructura gsm_dlci al reiniciar gsm mux. • http://www.openwall.com/lists/oss-security/2024/04/10/18 http://www.openwall.com/lists/oss-security/2024/04/10/21 http://www.openwall.com/lists/oss-security/2024/04/11/7 http://www.openwall.com/lists/oss-security/2024/04/11/9 http://www.openwall.com/lists/oss-security/2024/04/12/1 http://www.openwall.com/lists/oss-security/2024/04/12/2 http://www.openwall.com/lists/oss-security/2024/04/16/2 http://www.openwall.com/lists/oss-security/20 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
