CVE-2026-93279

EUVD-2026-86151
In the Linux kernel, the following vulnerability has been resolved:

staging: octeon: add missing tasklet_kill in cvm_oct_tx_shutdown

The TX cleanup tasklet can be scheduled by the watchdog IRQ handler
to execute cvm_oct_tx_do_cleanup. There can be a pending tasklet in
the queue which might run after the cvm_oct_remove() frees net_device
structures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it
iterates cvm_oct_device[] which is an array of netdevice pointers.
Add tasklet_kill() after free_irq() to ensure the tasklet is no longer
scheduled or running before teardown proceeds.
