high Tenable Cloud Security Plugin ID 451012

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: net_sched: hfsc: Fix a UAF
vulnerability in class with netem as child qdisc As described in Gerrard's report [1], we have a UAF case
when an hfsc class has a netem child qdisc. The crux of the issue is that hfsc is assuming that checking
for cl->qdisc->q.qlen == 0 guarantees that it hasn't inserted the class in the vttree or eltree (which is
not true for the netem duplicate case). This patch checks the n_active class variable to make sure that
the code won't insert the class in the vttree or eltree twice, catering for the reentrant case. [1]
