CVE-2022-48653
Description
A vulnerability was found in the Linux kernel's ICE network driver. This issue occurs when there is a double unplugging of auxiliary (aux) devices during a peer-initiated reset. In the IDC callback, which manages reset requests from auxiliary drivers, the function that handles the unplugging of auxiliary devices is called twice, once in the callback itself and again in the ice_prepare_for_reset function. This double call causes a "scheduling while atomic" bug, leading to potential system instability or crashes.
The vulnerability was identified as a medium severity issue with a CVSS v3 base score of 5.5, and it was resolved by correcting how the unplugging process is handled to avoid the double call.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
