Doc Text:
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.

Comment 2 Alex 2024-06-09 15:19:09 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2022-48653 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags REMOTE DANGER DISK NETWORK  ; these flags parsed automatically based on patche data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
