Description

linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-dell300x, linux-gcp, inux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-snapdragon vulnerabilities Brendan Dolan-Gavitt discovered that the aQuantia AQtion Ethernet device driver in the Linux kernel did not properly validate meta-data coming from the device. A local attacker who can control an emulated device can use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-43975) It was discovered that the UDF file system implementation in the Linux kernel could attempt to dereference a null pointer in some situations. An attacker could use this to construct a malicious UDF image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2022-0617) Lyu Tao discovered that the NFS implementation in the Linux kernel did not properly handle requests to open a directory on a regular file. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-24448) It was discovered that the YAM AX.25 device driver in the Linux kernel did not properly deallocate memory in some error conditions. A local privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2022-24959)
