https://notcve.org/view.php?id=CVE-2024-39507
In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix kernel crash problem in concurrent scenario When link status change, the nic driver need to notify the roce driver to handle this event, but at this time, the roce driver may uninit, then cause kernel crash. To fix the problem, when link status change, need to check whether the roce registered, and when uninit, need to wait link update finish. • https://git.kernel.org/stable/c/45e92b7e4e27a427de7e87d5c4d63d4ce7ba02ab https://git.kernel.org/stable/c/62b5dfb67bfa8bd0301bf3442004563495f9ee48 https://git.kernel.org/stable/c/6d0007f7b69d684879a0f598a042e40244d3cf63 https://git.kernel.org/stable/c/689de7c3bfc7d47e0eacc641c4ce4a0f579aeefa https://git.kernel.org/stable/c/b2c5024b771cd1dd8175d5f6949accfadbab7edd https://git.kernel.org/stable/c/12cda920212a49fa22d9e8b9492ac4ea013310a4 https://access.redhat.com/security/cve/CVE-2024-39507 https://bugzilla.redhat.com/show_bug.cgi?id=2297702 •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39506 – liquidio: Adjust a NULL pointer handling path in lio_vf_rep_copy_packet
https://notcve.org/view.php?id=CVE-2024-39506
In the Linux kernel, the following vulnerability has been resolved: liquidio: Adjust a NULL pointer handling path in lio_vf_rep_copy_packet In lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value, but then it is unconditionally passed to skb_add_rx_frag() which looks strange and could lead to null pointer dereference. lio_vf_rep_copy_packet() call trace looks like: octeon_droq_process_packets octeon_droq_fast_process_packets octeon_droq_dispatch_pkt octeon_create_recv_info ...search in the dispatch_list... ->disp_fn(rdisp->rinfo, ...) lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...) In this path there is no code which sets pg_info->page to NULL. So this check looks unneeded and doesn't solve potential problem. But I guess the author had reason to add a check and I have no such card and can't do real test. In addition, the code in the function liquidio_push_packet() in liquidio/lio_core.c does exactly the same. Based on this, I consider the most acceptable compromise solution to adjust this issue by moving skb_add_rx_frag() into conditional scope.

CVSS: 6.4EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39503 – netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type
https://notcve.org/view.php?id=CVE-2024-39503
In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type Lion Ackermann reported that there is a race condition between namespace cleanup in ipset and the garbage collection of the list:set type. The namespace cleanup can destroy the list:set type of sets while the gc of the set type is waiting to run in rcu cleanup. The latter uses data from the destroyed set which thus leads use after free. The patch contains the following parts: - When destroying all sets, first remove the garbage collectors, then wait if needed and then destroy the sets. - Fix the badly ordered "wait then remove gc" for the destroy a single set case. - Fix the missing rcu locking in the list:set type in the userspace test case. - Use proper RCU list handlings in the list:set type. The patch depends on c1193d9bbbd3 (netfilter: ipset: Add list flush to cancel_gc). • https://git.kernel.org/stable/c/c7f2733e5011bfd136f1ca93497394d43aa76225 https://git.kernel.org/stable/c/a24d5f2ac8ef702a58e55ec276aad29b4bd97e05 https://git.kernel.org/stable/c/c2dc077d8f722a1c73a24e674f925602ee5ece49 https://git.kernel.org/stable/c/653bc5e6d9995d7d5f497c665b321875a626161c https://git.kernel.org/stable/c/b93a6756a01f4fd2f329a39216f9824c56a66397 https://git.kernel.org/stable/c/97f7cf1cd80eeed3b7c808b7c12463295c751001 https://git.kernel.org/stable/c/970709a67696b100a57b33af1a3d75fc34b747eb https://git.kernel.org/stable/c/c0761d1f1ce1d5b85b5e82bbb714df12d • CWE-416: Use After Free •
