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.","cvssScore":8.4,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/28e84c6e2e6753ed238ea097b2842a32a6a6879b","tags":[]},{"url":"https://git.kernel.org/stable/c/4d2048466af9e2c960c5be6dcd317e3b657d268b","tags":[]},{"url":"https://git.kernel.org/stable/c/69259c627009bf7621010ae9e997dad2dad3339c","tags":[]},{"url":"https://git.kernel.org/stable/c/77f216f8de6221efb6f6c471bc9e598f1879825b","tags":[]},{"url":"https://git.kernel.org/stable/c/daa5b32cdf7db81a07ee2a91ce092a363e7754aa","tags":[]},{"url":"https://git.kernel.org/stable/c/fc65623524b5bf23baddc6ae688d954fba0d5de2","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
