VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.50
Description A divide-by-0 panic can occur in the padata mt helper() function when ps->chunk size is 0. This happens when the min chunk in the passed-in padata mt job structure is 0. The issue is resolved by ensuring that chunk size is at least 1, regardless of the input parameters.
Recommendations To resolve this issue, update the Linux kernel to version 6.6.50 or later. If updating is not possible, ensure that the chunk size is set to at least 1 in the padata do multithreaded() function to prevent the divide-by-0 panic.
