CVE-2026-68186

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: set haveexecfd only once the interpreter is opened loadmiscbinary raises bprm-haveexecfd as soon as it sees the 'O' or 'C' flag. This happens well before it opens the interpreter. If that open fails the flag stays set...

CVE-2026-68174

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix union collision of module and refcnt for dynamic events In 'struct traceeventcall', the 'module' pointer and the 'refcnt' atomic variable share the same memory space in a union.
