CVE-2022-49555

Summary: CVE-2022-49555 is tied to the Linux kernel Bluetooth subsystem (hci_qca). The issue arises when a timer is freed while still active due to code calling del_timer() instead of del_timer_sync(), risking timer-list corruption. The description notes that the hci_qca driver may trigger this, ...

CVE-2022-49555 Bluetooth: hci_qca: Use del_timer_sync() before freeing

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciqca: Use deltimersync 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 deltim...

CVE-2022-49474

CVE-2022-49474 (Linux kernel) affects the Bluetooth SCO path. The issue arises when connecting the same SCO socket twice (sco_sock_connect), which can create two sco_conn objects but only one is bound to the socket. If the socket closes before the SCO connection is established, the timer for the ...
