CVE-2026-53289 is a medium-severity flaw (CVSS 5.5) affecting linux kernel. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In the Linux kernel, the following vulnerability has been resolved: ice: fix NULL pointer dereference in ice_reset_all_vfs() ice_reset_all_vfs() ignores the return value of ice_vf_rebuild_vsi(). When the VSI rebuild fails (e.g. during NVM firmware update via nvmupdate64e), ice_vsi_rebuild() tears down the VSI on its error path, leaving txq_map and rxq_map as NULL. The subsequent unconditional call to ice_vf_post_vsi_rebuild() leads to a NULL po
