While in the case of \u201cRemote\u201d exploitation, hackers could achieve this by exploiting the structures that TIPC supports.\nPatching the CVE-2021-43267\nThe Linux Kernel versions between 5.10 and 5.15 are vulnerable to this security flaw, and in all major Linux distributions the TIPC module comes prebuilt, so, by default, it remains \u201coff,\u201d where users have to enable it for an implementation to be exposed to attack.\nBut, here, all the users who are affected by this bug can implement the released patch, since the experts have recommended users immediately apply the patch to keep themselves protected.\n\nJoin us: https://t.me/linux_news", "creation_timestamp": "2026-07-29T12:03:23.180793Z"}
