Summary
linux-gke vulnerabilities
Details

Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35788, LP: #2023577)

It was discovered that for some Intel processors the INVLPG instruction implementation did not properly flush global TLB entries when PCIDs are enabled. An attacker could use this to expose sensitive information (kernel memory) or possibly cause undesired behaviors. (LP: #2023220)
