Summary: linux-aws vulnerabilities

Details: Roger Pau Monné discovered that the Xen virtual block driver in the Linux kernel did not properly initialize memory pages to be used for shared communication with the backend. A local attacker could use this to expose sensitive information (guest kernel memory). (CVE-2022-26365) Roger Pau Monné discovered that the Xen paravirtualization frontend in the Linux kernel did not properly initialize memory pages to be used for shared communication with the backend. A local attacker could use this to expose sensitive information (guest kernel memory). (CVE-2022-33740) It was discovered that the Xen paravirtualization frontend in the Linux kernel incorrectly shared unrelated data when communicating with certain backends. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2022-33741)
