Linux Distros Unpatched Vulnerability : CVE-2024-36244

medium Nessus Plugin ID 229424

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: extend minimum interval restriction to entire cycle too It is possible for syzbot to side-step the restriction imposed by the blamed commit in the Fixes: tag, because the taprio UAPI permits a cycle-time different from (and potentially shorter than) the sum of entry intervals. We need one more restriction, which is that the cycle time itself must be larger than N * ETH_ZLEN bit times, where N is the number of schedule entries.
This restriction needs to apply regardless of whether the cycle time came from the user or was the implicit, auto-calculated value, so we move the existing cycle == 0 check outside the if (!new->cycle_time) branch. This way covers both conditions and scenarios. Add a selftest which illustrates the issue triggered by syzbot. (CVE-2024-36244)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution
