During the stack switch operation, processor does not deliver interrupts and exceptions, they are delivered once the first instruction after the stack switch is executed. An unprivileged system user could use this flaw to crash the system kernel resulting in DoS. This CVE-2018-10872 was assigned due to regression of CVE-2018-8897 in Red Hat Enterprise Linux 6.10 GA kernel. No other versions are affected by this CVE. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 18.04 LTS bionic | Not affected | | 17.10 artful | Not affected | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not affected | | linux-aws | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not affected | | linux-azure | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not affected | | linux-azure-edge | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | | linux-euclid | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-flo | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-gcp | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | | linux-gke | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Ignored end of standard support | | 14.04 LTS trusty | Not in release | | linux-goldfish | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-grouper | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-hwe | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | | linux-hwe-edge | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | | linux-kvm | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | | linux-lts-trusty | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-lts-utopic | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-lts-vivid | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-lts-wily | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-lts-xenial | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not affected | | linux-maguro | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-mako | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-manta | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | linux-oem | 18.04 LTS bionic | Not affected | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | | linux-raspi2 | 18.04 LTS bionic | Not affected | | 17.10 artful | Not affected | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | | linux-snapdragon | 18.04 LTS bionic | Not affected | | 17.10 artful | Not affected | | 16.04 LTS xenial | Not affected | | 14.04 LTS trusty | Not in release | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) ## Severity score breakdown CVSS version: CVSS v3.0 **Base score** 5.5 · Medium * Base metrics | Parameter | Value | | --- | --- | | Attack vector | Local | | Attack complexity | Low | | Privileges required | Low | | User interaction | None | | Scope | Unchanged | | Confidentiality impact | None | | Integrity impact | None | | Availability impact | High | * Scores | Parameter | Value | | --- | --- | | Base score | 5.5 · Medium | | Exploitability score | -
