jira VULN-67698 jira VULN-67697 cve CVE-2025-37797 commit-author Cong Wang <xiyou.wangcong@gmail.com> commit 3df275e This patch fixes a Use-After-Free vulnerability in the HFSC qdisc class handling. The issue occurs due to a time-of-check/time-of-use condition in hfsc_change_class() when working with certain child qdiscs like netem or codel. The vulnerability works as follows: 1. hfsc_change_class() checks if a class has packets (q.qlen != 0) 2. It then calls qdisc_peek_len(), which for certain qdiscs (e.g., codel, netem) might drop packets and empty the queue 3. The code continues assuming the queue is still non-empty, adding the class to vttree 4. This breaks HFSC scheduler assumptions that only non-empty classes are in vttree 5. Later, when the class is destroyed, this can lead to a Use-After-Free The fix adds a second queue length check after qdisc_peek_len() to verify the queue wasn't emptied. Fixes: 21f4d5c ("net_sched/hfsc: fix curve activation in hfsc_change_class()") Reported-by: Gerrard Tai <gerrard.tai@starlabs.sg> Reviewed-by: Konstantin Khlebnikov <koct9i@gmail.com> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Reviewed-by: Jamal Hadi Salim <jhs@mojatatu.com> Link: https://patch.msgid.link/20250417184732.943057-2-xiyou.wangcong@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> (cherry picked from commit 3df275e) Signed-off-by: Jonathan Maple <jmaple@ciq.com>

We are going to use this github action to do all the PR git commit processing. Since the kernel-src-tree is so large we need to minimize the wasted cycles on common checkout actions.
We will be reaching into our JIRA to check the state of each commits jira. In this we want to ensure that the target branch matches the defined branch for that product and validate that the CVE ID is also correct for the ticket. It will also check to confirm that the tickets are in progress and have time logged, if either are untrue then it will produce a warning. In the event there are Product or CVE mis matches it will block the PR and request changes.
