Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel’s ice driver related to devlink reloading. Specifically, a missing call to ice deinit hw() in the ice devlink reinit down() function, introduced by a previous commit, causes ice init hw() to fail with an -EBUSY error during devlink reinitialization. This failure, followed by removal of the ice driver, results in a NULL pointer dereference. The issue arises because control queues are not uninitialized, leading to the failure of ice init hw().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
