LIN1018-7362 : Security Advisory - linux - CVE-2021-28038

Created: Mar 7, 2021    Updated: Mar 23, 2021
Resolved Date: Mar 23, 2021
Found In Version: 10.18.44.1
Severity: Standard
Applicable for: Wind River Linux LTS 18
Component/s: Kernel

Description

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.
