Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: atmel: Fixed error handling in sndprotoprobe. The devicenode pointer is returned by ofparsephandle, with the refcount incremented. We should use ofnodeput on it after that operation. This function only calls ofnodeput in th...
