GHSA-J7VW-R676-53WR

Vulnerability from github – Published: 2022-05-24 17:43 – Updated: 2024-03-25 03:31

Details

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.

Severity

6.5 (Medium)
