Kiyin (ๅฐนไบฎ) discovered that the x25 implementation in the Linux kernel contained overflows when handling addresses from user space. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-35519) It was discovered that the fastrpc driver in the Linux kernel did not prevent user space applications from sending kernel RPC messages. A local attacker could possibly use this to gain elevated privileges. (CVE-2021-28375) It was discovered that the TIPC protocol implementation in the Linux kernel did not properly validate passed encryption key sizes. A local attacker could use this to cause a denial of service (system crash). (CVE-2021-29646) It was discovered that a race condition existed in the netfilter subsystem of the Linux kernel when replacing tables. A local attacker could use this to cause a denial of service (system crash). (CVE-2021-29650) Arnd Bergmann discovered that the video4linux subsystem in the Linux kernel did not properly deallocate memory in some situations. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-30002) ...
