{"id":"USN-6205-1","summary":"linux-gke vulnerabilities","details":"Hangyu Hua discovered that the Flower classifier implementation in the\nLinux kernel contained an out-of-bounds write vulnerability. An attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2023-35788, LP: #2023577)\n\nIt was discovered that for some Intel processors the INVLPG instruction\nimplementation did not properly flush global TLB entries when PCIDs are\nenabled. An attacker could use this to expose sensitive information\n(kernel memory) or possibly cause undesired behaviors.
