CVSS: 7.0EPSS: 0%CPEs: 6EXPL: 0CVE-2023-6531 – Kernel: gc's deletion of an skb races with unix_stream_read_generic() leading to uaf
https://notcve.org/view.php?id=CVE-2023-6531
A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on. Se encontró una falla de use-after-free en el kernel de Linux debido a un problema de ejecución en la eliminación de ejecución de SKB por parte del recolector de basura de Unix con unix_stream_read_generic() en el socket en el que el SKB está en cola. Linux suffers from an io_uring use-after-free vulnerability due to broken unix GC interaction. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/security/cve/CVE-2023-6531 https://bugzilla.redhat.com/show_bug.cgi?id=2253034 https://lore.kernel.org/all/c716c88321939156909cfa1bd8b0faaf1c804103.1701868795.git.asml.silence@gmail.com • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-51780
An issue was discovered in the Linux kernel before 6.6.8. do_vcc_ioctl in net/atm/ioctl.c has a use-after-free because of a vcc_recvmsg race condition. Se descubrió un problema en el kernel de Linux anterior a 6.6.8. do_vcc_ioctl en net/atm/ioctl.c tiene un use after free debido a una condición de ejecución vcc_recvmsg. A use-after-free flaw was found in the Linux kernel's net/atm/ioctl.c (ATM networking technology driver): do_vcc_ioctl in net/atm/ioctl.c is vulnerable to use-after-free due to a race condition in vcc_recvmsg. This issue can allow an attacker to possibly gain unauthorized access, escalate privileges, or cause the system to crash. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.6.8 https://github.com/torvalds/linux/commit/24e90b9e34f9e039f56b5f25f6e6eb92cdd8f4b3 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://lists.debian.org/debian-lts-announce/2024/01/msg00005.html https://security.netapp.com/advisory/ntap-20240419-0001 https://access.redhat.com/security/cve/CVE-2023-51780 https://bugzilla.redhat.com/show_bug.cgi?id=2257682 • CWE-416: Use After Free •

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 •
