A privileged attacker could possibly use this\nto cause a denial of service (system crash) or possibly execute arbitrary\ncode. (CVE-2021-20292)\n\nOlivier Benjamin, Norbert Manthey, Martin Mazein, and Jan H. Schönherr\ndiscovered that the Xen paravirtualization backend in the Linux kernel did\nnot properly propagate errors to frontend drivers in some situations. An\nattacker in a guest VM could possibly use this to cause a denial of service\n(host domain crash). (CVE-2021-26930)\n\nJan Beulich discovered that multiple Xen backends in the Linux kernel did\nnot properly handle certain error conditions under paravirtualization.

An attacker could use this to cause a denial of\nservice (system crash). (CVE-2021-29264)\n\nIt was discovered that the USB/IP driver in the Linux kernel contained race\nconditions during the update of local and shared status. An attacker could\nuse this to cause a denial of service (system crash). (CVE-2021-29265)\n\nIt was discovered that a race condition existed in the netfilter subsystem\nof the Linux kernel when replacing tables.
