CVE-2024-43102 – umtx Kernel panic or Use-After-Free
https://notcve.org/view.php?id=CVE-2024-43102
Concurrent removals of certain anonymous shared memory mappings by using the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTX_SHM_DESTROY sub-request in parallel can panic the kernel or enable further Use-After-Free attacks, potentially including code execution or Capsicum sandbox escape. • https://security.freebsd.org/advisories/FreeBSD-SA-24:14.umtx.asc • CWE-416: Use After Free CWE-911: Improper Update of Reference Count •

CVE-2024-20284 – Cisco NX-OS Software Python Parser Escape Vulnerability
https://notcve.org/view.php?id=CVE-2024-20284
A vulnerability in the Python interpreter of Cisco NX-OS Software could allow an authenticated, low-privileged, local attacker to escape the Python sandbox and gain unauthorized access to the underlying operating system of the device. The vulnerability is due to insufficient validation of user-supplied input. ... A successful exploit could allow an attacker to escape the Python sandbox and execute arbitrary commands on the underlying operating system with the privileges of the authenticated user. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-psbe-ce-YvbTn5du https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/105x/programmability/cisco-nexus-9000-series-nx-os-programmability-guide-105x/m-n9k-python-api-101x.html?bookSearch=true#concept_A2CFF094ADCB414C983EA06AD8E9A410 • CWE-693: Protection Mechanism Failure •
