Linux kernel vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

Ubuntu 20.04 LTS
Ubuntu 18.04 LTS
Ubuntu 16.04 ESM

Summary

Several security issues were fixed in the kernel. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-29661)

De4dCr0w of 360 Alpha Lab discovered that the BPF verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker could use this to expose sensitive information (kernel memory) or possibly execute arbitrary code. (CVE-2021-3444)

kernel: use-after-free in route4_change() in net/sched/cls_route.c (CVE-2021-3715)

Linux kernel vulnerabilities\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n-   Ubuntu 20.04 LTS\n-   Ubuntu 18.04 LTS\n-   Ubuntu 16.04 ESM\n\nSummary\n\nSeveral security issues were fixed in the kernel. A local attacker could use this to cause a denial of\nservice (system crash) or possibly expose sensitive information (kernel\nmemory). A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. \n(CVE-2020-29661)\n\nDe4dCr0w of 360 Alpha Lab discovered that the BPF verifier in the Linux\nkernel did not properly handle mod32 destination register truncation\nwhen the source register was known to be 0. A local attacker could use\nthis to expose sensitive information (kernel memory) or possibly execute\narbitrary code. (CVE-2021-3444)\n\nkernel: use-after-free in route4_change() in net/sched/cls_route.c \n(CVE-2021-3715)\n\nUpdate instructions\n\nThe problem can be corrected by updating your kernel livepatch to the\nfollowing versions:\n\nUbuntu 20.04 LTS\n    gcp - 82.2\n    generic - 82.2\n    gke - 82.2\n    gkeop - 82.2\n    lowlatency - 82.2\n\nUbuntu 18.04 LTS\n    generic - 82.1\n    generic - 82.2\n    gke - 82.1\n    gke - 82.2\n    gkeop - 82.2\n    lowlatency - 82.1\n    lowlatency - 82.2\n    oem - 82.1\n    oem - 82.2\n\nUbuntu 16.04 ESM\n    generic - 82.1\n    generic - 82.2\n    lowlatency - 82.1\n    lowlatency - 82.2\n\nSupport Information\n\nKernels older than the levels listed below do not receive livepatch\nupdates.
