  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: saa7164: fix cleanup on resource allocation failure\n\nsaa7164_dev_setup() adds the device to the global saa7164_devlist before\nrequesting the PCI BAR memory regions.\n\nIf get_resources() fails, saa7164_dev_setup() decrements the device count\nand returns an error, but leaves the device on saa7164_devlist. The probe\nerror path then frees the device, leaving a dangling entry on the global\nlist.\n\nReuse the existing MMIO mapping error path to remove the device from\nsaa7164_devlist and decrement the device count before returning.\n\nAlso release BAR0 if it was successfully requested but the BAR2 request\nfails.",
