CVE-2023-5178 – Kernel: use after free in nvmet_tcp_free_crypto in nvme
https://notcve.org/view.php?id=CVE-2023-5178
A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation. Se encontró una vulnerabilidad de use-after-free en drivers/nvme/target/tcp.c` en `nvmet_tcp_free_crypto` debido a un error lógico en el subsistema NVMe-oF/TCP en el kernel de Linux. Este problema puede permitir que un usuario malintencionado cause un problema de use-after-free y double-free, lo que puede permitir la ejecución remota de código o provocar una escalada de privilegios locales en caso de que el atacante ya tenga privilegios locales. • https://github.com/rockrid3r/CVE-2023-5178 https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7548 https://access.redhat.com/errata/RHSA-2023:7549 https://access.redhat.com/errata/RHSA-2023:7551 https://access.redhat.com/errata/RHSA-2023:7554 https://access.redhat.com/errata/RHSA-2023:7557 https://access.redhat.com/errata/RHSA-2023 • CWE-416: Use After Free •
