libcurl: libcurl: Use-after-free vulnerability leading to Denial of Service

A flaw was found in libcurl. This use-after-free vulnerability occurs when an application configures an HTTP/2 stream-dependency tree and then performs a sequence of operations involving curleasyreset and curleasycleanup. During the final cleanup, libcurl attempts to access memory that has alread...

CVE-2026-72212

A flaw was found in the Linux kernel's memory hotplug subsystem.
