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

  - gpio: pca953x: fix pca953x_irq_bus_sync_unlock regmap lock Locking is disabled in the regmap config as     this driver uses its own lock. This means that all calls to regmap functions (read or write) must hold the     i2c_lock. The function pca953x_irq_bus_sync_unlock() did not do this, and it was therefore possible that     multiple threads could cause an incorrect register to be read/written. A previous patch partly fixed this,     but only protected the write to the interrupt mask register, and not the read from the direction register.
    (CVE-2026-74733)

Note that Nessus relies on the presence of the package as reported by the vendor.
