https://notcve.org/view.php?id=CVE-2022-1974
A use-after-free flaw was found in the Linux kernel's NFC core functionality due to a race condition between kobject creation and delete. This vulnerability allows a local attacker with CAP_NET_ADMIN privilege to leak kernel information. Se ha encontrado un fallo de uso de memoria previamente liberada en la funcionalidad del núcleo NFC del kernel de Linux debido a una condición de carrera entre la creación y el borrado de kobject. Esta vulnerabilidad permite a un atacante local con privilegios CAP_NET_ADMIN filtrar información del kernel • https://github.com/torvalds/linux/commit/da5c0f119203ad9728920456a0f52a6d850c01cd • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-416: Use After Free •

CVE-2022-1729 – kernel: race condition in perf_event_open leads to privilege escalation
https://notcve.org/view.php?id=CVE-2022-1729
A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. Se ha encontrado una condición de carrera en el kernel de Linux en la función perf_event_open() que puede ser explotada por un usuario no privilegiado para conseguir privilegios de root. El bug permite construir varias primitivas de explotación como un filtrado de información de direcciones del kernel, una ejecución arbitraria, etc A use-after-free flaw was found in the Linux kernel’s performance events functionality. A user triggers a race condition in setting up performance monitoring between the leading PERF_TYPE_TRACEPOINT and sub PERF_EVENT_HARDWARE plus the PERF_EVENT_SOFTWARE using the perf_event_open() function with these three types. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3ac6487e584a1eb54071dbe1212e05b884136704 https://security.netapp.com/advisory/ntap-20230214-0006 https://www.openwall.com/lists/oss-security/2022/05/20/2 https://access.redhat.com/security/cve/CVE-2022-1729 https://bugzilla.redhat.com/show_bug.cgi?id=2086753 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-366: Race Condition within a Thread •
