CVE-2026-93278

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

staging: octeon: add missing napi_disable in cvm_oct_rx_shutdown

cvm_oct_rx_shutdown calls free_irq and netif_napi_del without

disabling the napi instance first. As the free_irq only waits

for completion of hard interrupt handlers, the napi poll

function could still be active. If cvm_oct_remove proceeds to

free the plat structure (which holds the NAPI instances), the

active poll function will access freed memory, resulting in a

use-after-free crash.
