Summary
linux-oem-6.1 vulnerabilities
Details

Tom Dohrmann discovered that the Secure Encrypted Virtualization (SEV) implementation for AMD processors in the Linux kernel contained a race condition when accessing MMIO registers. A local attacker in a SEV guest VM could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-46813)

It was discovered that the io_uring subsystem in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46862)
