The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - i2c: i801: fix hardware state machine corruption in error path A severe livelock and subsequent Hung Task     panic were observed in the i2c-i801 driver during concurrent Fuzzing. The crash is caused by an     unconditional hardware register cleanup in the error handling path of i801_access(). When i801_check_pre()     fails (e.g., returning -EBUSY because the SMBus controller is actively used by BIOS/ACPI), the kernel does     not actually acquire the hardware ownership. However, the code jumps to the 'out' label and executes:
    iowrite8(SMBHSTSTS_INUSE_STS | STATUS_FLAGS, SMBHSTSTS(priv)); This forcefully clears the INUSE_STS lock     and resets the hardware status flags without owning the controller. Doing so interrupts ongoing BIOS/ACPI     transactions and totally corrupts the SMBus hardware state machine. Consequently, all subsequent     i801_access() calls fail at the pre-check stage, triggering an endless stream of SMBus is busy, can't use     it! error logs. Over a slow serial console, this printk flood monopolizes the CPU (Console Livelock),     starving other processes trying to acquire the mmap_lock down_read semaphore, ultimately triggering the     hung task watchdog. Fix this by moving the 'out' label below the hardware register cleanup. If     i801_check_pre() fails, we safely bypass the iowrite8() and only release the software locks (pm_runtime     and mutex), strictly adhering to the rule of not releasing resources that were never acquired.
