Ubuntu: USN-5003-1 (CVE-2021-3600): Linux kernel vulnerabilities

Description
Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.From USN-5003-1:Norbert Slusarek discovered a race condition in the CAN BCM networking protocol of the Linux kernel leading to multiple use-after-free vulnerabilities. A local attacker could use this issue to execute arbitrary code. (CVE-2021-3609)It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code. (CVE-2021-3600)Or Cohen discovered that the SCTP implementation in the Linux kernel contained a race condition in some situations, leading to a use-after-free condition. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-23133)
