CVE-2022-49555
|
| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_qca: Use del_timer_sync() before freeing
While looking at a crash report on a timer list being corrupted, which
usually happens when a timer is freed while still active. This is
commonly triggered by code calling del_timer() instead of
del_timer_sync() just before freeing.
One possible culprit is the hci_qca driver, which does exactly that.
Eric mentioned that wake_retrans_timer could be rearmed via the work
queue, so also move the destruction of the work queue before
del_timer_sync(). |
