What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that include this patch to mitigate the issue.
Description
A use-after-free vulnerability in the Linux kernel's net/ncsi component was fixed by disabling the ncsi work before freeing its associated structure. This flaw could cause kernel panic or memory corruption due to the work function running after the device is freed.
