UBUNTU-CVE-2024-47728

In the Linux kernel, the following vulnerability has been resolved: bpf: Zero former ARGPTRTOLONG,INT args in case of error For all non-tracing helpers which formerly had ARGPTRTOLONG,INT as input arguments, zero the value for the case of an error as otherwise it could leak memory. For tracing, i...
