In the Linux kernel, the following vulnerability has been resolved: tracing: Fix NULL pointer dereference in funcsetflag funcsetflag dereferences tr-currenttraceflags before verifying that the current tracer is actually the function tracer. When the active tracer has been switched away from...

CVE-2026-64028

A flaw was found in the Linux kernel's tracing subsystem. The histfieldname function, responsible for handling field names, can return a NULL value if a long variable name in a fully-qualified reference causes snprintf truncation. This unexpected NULL return can lead to a NULL pointer dereference...

CVE-2026-64173

A flaw was found in the Linux kernel. An issue in the tracing subsystem's memory management could lead to incorrect deallocation of tracing map elements. Specifically, the system attempts to free memory that was never successfully allocated, which can result in memory corruption. This vulnerabili...
