The vulnerability of the Linux operating system’s interrupt handler `snd_korg1212_interrupt` allows a hacker to cause a service failure.

The vulnerability of the interrupt handler sndkorg1212interrupt in the Linux kernel’s sound/pci/korg1212/snd-korg1212.ko module is related to the swapping of the zero pointer. Exploiting this vulnerability could allow an attacker to cause a system failure when a Korg 1212 device is connected. Thi...

The vulnerability of the lolainterrupt interrupt handler implementation in Linux kernels allows a hacker to cause a system failure.

The vulnerability of the interrupt handler lolainterrupt in the sound/pci/lola/snd-lola.ko module of the Linux operating system is related to the swapping of the zero pointer. Exploiting this vulnerability can allow an attacker to cause a system failure when a Digigram Lola device, which appears ...

UBUNTU-CVE-2019-3887

A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister MSR access with nested=1 virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash t...

Kernel: error in exception handling leads to DoS

A flaw was found in the way the Linux kernel handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the...

What we’ve got here is failure to communicate: OS vendors misread CPU docs, create flaw

In a memorable scene from “Jumpin’ Jack Flash,” Whoopi Goldberg struggles to understand the lyrics of the eponymous song from the Rolling Stones, as she pleads: “Mick, Mick, Mick, speak English!” It appears that multiple operating system vendors had similar trouble interpreting Intel and AMD...
