CVE-2022-50374

CVE-2022-50374 affects the Linux kernel Bluetooth stack (hci_ldisc/hci_serdev). The issue is a missing handling of percpu_init_rwsem() failure, leading to a NULL pointer dereference in hci_uart_tty_close() because rcu_sync_enter() can be called without rcu_sync_init() after hci_uart_tty_open() ig...

CVE-2023-53173

In CVE-2023-53173, the Linux kernel tty pcn_uart driver had a memory leak when using debugfs_lookup() because the returned object wasn’t always released with dput(). The recommended fix is to call debugfs_lookup_and_remove() to perform the lookup and cleanup in one step, mitigating the leak.
