There can be a pending tasklet in\nthe queue which might run after the cvm_oct_remove() frees net_device\nstructures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it\niterates cvm_oct_device[] which is an array of netdevice pointers.\nAdd tasklet_kill() after free_irq() to ensure the tasklet is no longer\nscheduled or running before teardown proceeds.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/03d12490afd1198310ad0aba42462329832eb739","tags":[]},{"url":"https://git.kernel.org/stable/c/2c0c9956596e48654bb4855e2a0742748a0826a7","tags":[]},{"url":"https://git.kernel.org/stable/c/32efcb6d5f4e3f030e7b0a3ba5c6c0684dd07486","tags":[]},{"url":"https://git.kernel.org/stable/c/41a79bd9e5a74f8f483b3b206d10567912874fb4","tags":[]},{"url":"https://git.kernel.org/stable/c/a77efd85e0d48c877f66d2bc3ab89cc1b8dacd19","tags":[]},{"url":"https://git.kernel.org/stable/c/b6365e4186322858a82c8713b1d0bd209c8e765a","tags":[]},{"url":"https://git.kernel.org/stable/c/b9af44b0d20b2247c4eb0ea5cfca907d643eea50","tags":[]},{"url":"https://git.kernel.org/stable/c/d15226338dfaa84ffff142d32723cdf74d0c47c4","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
