Description
In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Do not double dequeue a configuration request
Some of our devices crash in tb_cfg_request_dequeue():
general protection fault, probably for non-canonical address 0xdead000000000122
CPU: 6 PID: 91007 Comm: kworker/6:2 Tainted: G U W 6.6.65
RIP: 0010:tb_cfg_request_dequeue+0x2d/0xa0
Call Trace:
<TASK>
? tb_cfg_request_dequeue+0x2d/0xa0
tb_cfg_request_work+0x33/0x80
worker_thread+0x386/0x8f0
kthread+0xed/0x110
ret_from_fork+0x38/0x50
ret_from_fork_asm+0x1b/0x30
The circumstances are unclear, however, the theory is that
tb_cfg_request_work() can be scheduled twice for a request:
first time via frame.callback from ring_work() and second
time from tb_cfg_request(). Both times kworkers will execute
tb_cfg_request_dequeue(), which results in double list_del()
from the ctl->request_queue (the list poison deference hints
at it: 0xdead000000000122).
Do not dequeue requests that don't have TB_CFG_REQUEST_ACTIVE
bit set.
