  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nnetfilter: conntrack_irc: fix possible out-of-bounds read\nWhen parsing fails after we've matched the command string we\nshould bail out instead of trying to match a different command.\nThis helper should be deprecated, given prevalence of TLS I doubt it has\nany relevance in 2026.", "A flaw was found in the Linux kernel's netfilter conntrack_irc module. This vulnerability allows for a possible out-of-bounds read. When parsing network traffic, if a command string is matched but subsequent parsing fails, the system does not properly exit, leading to the flaw. This could potentially allow an attacker to cause a denial of service or disclose sensitive information." ],
