CVE-2026-43265

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for x86 architectures. A local user or a malicious guest operating system could manipulate the virtual CPU vCPU state by injecting events while the vCPU is in a blocking state. This could lead to a spurious exit to userspace,...

CVE-2026-43240

A flaw was found in the Linux kernel's x86/kexec component. When a second-stage kernel is booted with a memory-limiting command, the Integrity Measurement Architecture IMA kexec buffer may be located outside the accessible memory range. This can lead to a kernel panic, effectively causing a Denia...
