Summary
linux vulnerabilities
Details

Reima Ishii discovered that the nested KVM implementation for Intel x86 processors in the Linux kernel did not properly validate control registers in certain situations. An attacker in a guest VM could use this to cause a denial of service (guest crash). (CVE-2023-30456)

It was discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel did not properly handle network packets in certain conditions, leading to a use after free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4921)

It was discovered that a race condition existed in the SCSI Emulex LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF and re-scanning an HBA FCF table, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-24855)
