CVE-2021-28038 log

Severity Low
Remote No
Type Denial of service
An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931. The issue is fixed in kernel versions 5.11.4 and 5.10.21.
