CVE-2026-43445

A flaw was found in the Linux kernel's e1000 and e1000e network drivers. When an error occurs during the mapping of transmit TX buffers, an off-by-one error in the Direct Memory Access DMA cleanup process can lead to a memory leak. This issue results in the gradual exhaustion of system resources,...

CVE-2026-43401

A flaw was found in the Linux kernel's intelpstate component. This vulnerability arises when the system is booted with the "nosmt" parameter, causing a critical error known as a null pointer dereference in the updatecpuqosrequest function. Such an error can lead to system instability and...

CVE-2026-43344

A flaw was found in the Linux kernel's performance monitoring unit perf/x86/intel/uncore subsystem. This vulnerability arises from incorrect die ID initialization and lookup, particularly when certain CPUs are offline or when Non-Uniform Memory Access NUMA is disabled. As a consequence, performan...
