Kyle Zeng discovered that the Network Queuing and Scheduling subsystem of the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-29581) Bing-Jhong Billy Jheng discovered that the io_uring subsystem in the Linux kernel contained in integer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1116) Jann Horn discovered that the Linux kernel did not properly enforce seccomp restrictions in some situations. A local attacker could use this to bypass intended seccomp sandbox restrictions. (CVE-2022-30594)
