The vulnerability of the `synproxy_parse_options()` function in the `net/netfilter/nf_synproxy_core.c` module of the `netfilter` component of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the synproxyparseoptions function in the net/netfilter/nfsynproxycore.c module of the netfilter component of the Linux operating system is related to reading beyond the buffer boundaries. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2021-47245

A vulnerability was found in the Linux kernel's netfilter system, in the synproxy TCP option parser. This issue allows the parser to read one byte beyond its intended limit when processing TCP options, which could lead to unexpected behavior or crash. Mitigation Red Hat has investigated whether a...
