CVE-2023-4134

A use-after-free vulnerability was found in the cyttsp4_core driver in the Linux kernel. This issue occurs in the device cleanup routine due to a possible rearming of the watchdog_timer from the workqueue. This could allow a local user to crash the system, causing a denial of service.

A use-after-free vulnerability was found in the cyttsp4_core driver in the Linux kernel. This issue occurs in the device cleanup routine due to a possible rearming of the watchdog_timer from the workqueue. This could allow a local user to crash the system, causing a denial of service.

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

i40e: Fix kernel crash during module removal

The driver incorrectly frees client instance and subsequent i40e module removal leads to kernel crash.

Reproducer:

1. Do ethtool offline test followed immediately by another one host# ethtool -t eth0 offline; ethtool -t eth0 offline
2. Remove recursively irdma module that also removes i40e module host# modprobe -r irdma

Two offline tests cause IRDMA driver failure (ETIMEDOUT) and this failure is indicated back to i40e_client_subtask() that calls i40e_client_del_instance() to free client instance referenced by pf->cinst and sets this pointer to NULL. During the module removal i40e_remove() calls i40e_lan_del_device() that dereferences pf->cinst that is NULL -> crash. Do not remove client instance when client open callbacks fails and just clear __I40E_CLIENT_INSTANCE_OPENED bit. The driver also needs to take care about this situation (when netdev is up and client is NOT opened) in i40e_notify_client_of_netdev_close() and calls client close callback only when __I40E_CLIENT_INSTANCE_OPENED is set.(CVE-2022-48688)
