Summary

linux-bluefield vulnerabilities

Details

It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3669)

It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. (CVE-2022-2196)

Gerald Lee discovered that the USB Gadget file system implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-4382)

It was discovered that the RNDIS USB driver in the Linux kernel contained an integer overflow vulnerability. A local attacker with physical access could plug in a malicious USB device to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-23559)
