Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: sfp: fixed a memory leak in sfpprobe The sfpprobe function allocates a memory chunk from the sfp structure using sfpalloc. When devmaddaction fails, the sfp structure is not freed, resulting in a memory leak. We should use...
