Technical description

In the Linux kernel, the following vulnerability has been resolved:

media: v4l: async: Fix duplicated list deletion

The list deletion call dropped here is already called from the

helper function in the line before. Having a second list_del()

call results in either a warning (with CONFIG_DEBUG_LIST=y):

list_del corruption, c46c8198->next is LIST_POISON1 (00000100)

If CONFIG_DEBUG_LIST is disabled the operation results in a

kernel error due to NULL pointer dereference.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
