AI-suggested
A fix is available that removes the broken MOST I2C driver from the staging area. Users should update to linux-hwe-edge kernel versions 6.8.0-1051.51~22.04.1 or later where the driver has been removed. No additional mitigation is required as the driver is no longer included.
Description
A vulnerability in the Linux kernel's MOST I2C driver was resolved by removing the broken driver from staging. The driver had been non-functional for five years due to a NULL pointer dereference caused by an interface device pointer not being set before registration. This issue could cause a system crash if the driver is probed. The fix involves removing the faulty driver entirely. This vulnerability affects specific linux-hwe-edge kernel versions prior to 6.8.0-1051.51~22.04.1 and similar builds. The issue is rated medium severity and no known exploits are reported in the wild.
