In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: flush pending destroy work before exit_net release Similar to 2c9f0293280e ("netfilter: nf_tables: flush pending destroy work before netlink notifier") to address a race between exit_net and the destroy workqueue. The trace below shows an element to be released via destroy workqueue while exit_net path (triggered via module removal) has already released the set that is used in such transaction.

CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-35895 – bpf, sockmap: Prevent lock inversion deadlock in map delete elem
https://notcve.org/view.php?id=CVE-2024-35895
In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Prevent lock inversion deadlock in map delete elem syzkaller started using corpuses where a BPF tracing program deletes elements from a sockmap/sockhash map. Because BPF tracing programs can be invoked from any interrupt context, locks taken during a map_delete_elem operation must be hardirq-safe. Otherwise a deadlock due to lock inversion is possible, as reported by lockdep: CPU0 CPU1 ---- ---- lock(&htab->buckets[i].lock); local_irq_disable(); lock(&host->lock); lock(&htab->buckets[i].lock); <Interrupt> lock(&host->lock); Locks in sockmap are hardirq-unsafe by design. We expects elements to be deleted from sockmap/sockhash only in task (normal) context with interrupts enabled, or in softirq context. Detect when map_delete_elem operation is invoked from a context which is _not_ hardirq-unsafe, that is interrupts are disabled, and bail out with an error. Note that map updates are not affected by this issue. BPF verifier does not allow updating sockmap/sockhash from a BPF tracing program today. • https://git.kernel.org/stable/c/604326b41a6fb9b4a78b6179335decee0365cd8c https://git.kernel.org/stable/c/f7990498b05ac41f7d6a190dc0418ef1d21bf058 https://git.kernel.org/stable/c/dd54b48db0c822ae7b520bc80751f0a0a173ef75 https://git.kernel.org/stable/c/d1e73fb19a4c872d7a399ad3c66e8ca30e0875ec https://git.kernel.org/stable/c/a44770fed86515eedb5a7c00b787f847ebb134a5 https://git.kernel.org/stable/c/668b3074aa14829e2ac2759799537a93b60fef86 https://git.kernel.org/stable/c/913c30f827e17d8cda1da6eeb990f350d36cb69b https://git.kernel.org/stable/c/6af057ccdd8e7619960aca1f0428339f2 •

In the Linux kernel, the following vulnerability has been resolved: net/sched: act_skbmod: prevent kernel-infoleak syzbot found that tcf_skbmod_dump() was copying four bytes from kernel stack to user space [1]. The issue here is that 'struct tc_skbmod' has a four bytes hole. We need to clear the structure before filling fields.
