SUSE CVE-2026-90291

In the Linux kernel, the following vulnerability has been resolved: module/dups: Fix use-after-free in kmoddupreq lifetime handling The kmod dups code uses RCU to ensure that a kmoddupreq instance is freed only after it is no longer referenced. When releasing an instance, the kmodduprequestdelete...

CVE-2026-93181

CVE-2026-93181 affects the Linux kernel in the perf/x86/intel/uncore subsystem. The root cause is an incorrect call ordering: in the CPU online path, uncore_box_ref() was invoked before uncore_change_context(), so the gate on box->cpu >= 0 always failed and the uncore box was never initiali...
