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.

CVE-2024-28956 is an information disclosure vulnerability affecting some Intel processors. It involves exposure of sensitive information through shared microarchitectural structures during transient execution. The vulnerability requires local authenticated access and has a medium severity rating with a CVSS score of 5.7. Red Hat has released updates for the Linux kernel and microcode_ctl packages to address this issue in Red Hat Enterprise Linux 9. Users must apply these updates and reboot their systems to mitigate the vulnerability.
