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)
Xingyuan Mo and Gengjia Chen discovered that the io_uring subsystem in the
Linux kernel did not properly handle locking when IOPOLL mode is being
used. A local attacker could use this to cause a denial of service (system
crash). (CVE-2023-2430)
Wei Chen discovered that the InfiniBand RDMA communication manager
implementation in the Linux kernel contained an out-of-bounds read
vulnerability. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-2176)
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)
