SUSE CVE-2026-46272

In the Linux kernel, the following vulnerability has been resolved: coresight: tmc-etr: Fix race condition between sysfs and perf mode When trying to run perf and sysfs mode simultaneously, the WARNON in tmcetrenablehw is triggered sometimes: WARNING: CPU: 42 PID: 3911571 at...

CVE-2026-46264

A flaw was found in the Linux kernel's drm/xe/pf component. This vulnerability arises during the initialization of the sysfs interface, where an error in devmaddactionorreset can cause a cleanup action to execute on an uninitialized kernel object. This can lead to a use-after-free condition, whic...

CVE-2026-46272

A flaw was found in the Linux kernel's Coresight Trace Memory Controller TMC Embedded Trace Router ETR driver. A race condition can occur when both the sysfs and perf modes are used simultaneously. This can lead to a kernel warning, potentially causing system instability or unexpected behavior...
