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 •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-6932 – Use-after-free in Linux kernel's ipv4: igmp component
https://notcve.org/view.php?id=CVE-2023-6932
A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread. We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. Una vulnerabilidad de use after free en el componente ipv4: igmp del kernel de Linux se puede explotar para lograr una escalada de privilegios local. Se puede aprovechar una condición de ejecución para provocar que un temporizador se registre por error en un objeto bloqueado de lectura de RCU que es liberado por otro subproceso. Recomendamos actualizar el commit anterior e2b706c691905fe78468c361aaabc719d0a496f1. A race condition has been discovered in the Linux kernel's Internet Group Management Protocol (IGMP) implementation. • http://packetstormsecurity.com/files/177029/Kernel-Live-Patch-Security-Notice-LSN-0100-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=e2b706c691905fe78468c361aaabc719d0a496f1 https://kernel.dance/e2b706c691905fe78468c361aaabc719d0a496f1 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://lists.debian.org/debian-lts-announce/2024/01/msg00005.html https://access.redhat.com/security/cve/CVE-2023-6932 https://bugzilla.redhat.com/show_bug.cgi?id=2255283 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2023-6931 – Out-of-bounds write in Linux kernel's Performance Events system component
https://notcve.org/view.php?id=CVE-2023-6931
A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. Se puede aprovechar una vulnerabilidad de escritura fuera de los límites en la pila en el componente del sistema Performance Events del kernel de Linux para lograr una escalada de privilegios local. El read_size de un perf_event puede desbordarse, lo que lleva a un incremento o escritura fuera de los límites en la pila en perf_read_group(). Recomendamos actualizar al commit anterior 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. A flaw was found in the Linux kernel's Performance Events system component. • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=382c27f4ed28f803b1f1473ac2d8db0afc795a1b https://kernel.dance/382c27f4ed28f803b1f1473ac2d8db0afc795a1b https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://lists.debian.org/debian-lts-announce/2024/01/msg00005.html https://access.redhat.com/security/cve/CVE-2023-6931 https://bugzilla.redhat.com/show_bug.cgi?id=2252731 • CWE-787: Out-of-bounds Write •
