First published: Thu Feb 09 2023(Updated: )

Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-0179) It was discovered that the Netronome Ethernet driver in the Linux kernel contained 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-2022-3545) It was discovered that the Intel i915 graphics driver in the Linux kernel did not perform a GPU TLB flush in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-4139) Tamás Koczka discovered that the Bluetooth L2CAP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-42895)
