https://notcve.org/view.php?id=CVE-2024-39509
In the Linux kernel, the following vulnerability has been resolved: HID: core: remove unnecessary WARN_ON() in implement() Syzkaller hit a warning [1] in a call to implement() when trying to write a value into a field of smaller size in an output report. Since implement() already has a warn message printed out with the help of hid_warn() and value in question gets trimmed with: ... value &= m; ... WARN_ON may be considered superfluous. Remove it to suppress future syzkaller triggers.

CVSS: 7.0EPSS: 0%CPEs: 3EXPL: 0CVE-2024-39508 – io_uring/io-wq: Use set_bit() and test_bit() at worker->flags
https://notcve.org/view.php?id=CVE-2024-39508
In the Linux kernel, the following vulnerability has been resolved: io_uring/io-wq: Use set_bit() and test_bit() at worker->flags Utilize set_bit() and test_bit() on worker->flags within io_uring/io-wq to address potential data races. The structure io_worker->flags may be accessed through various data paths, leading to concurrency issues. When KCSAN is enabled, it reveals data races occurring in io_worker_handle_work and io_wq_activate_free_worker functions. BUG: KCSAN: data-race in io_worker_handle_work / io_wq_activate_free_worker write to 0xffff8885c4246404 of 4 bytes by task 49071 on cpu 28: io_worker_handle_work (io_uring/io-wq.c:434 io_uring/io-wq.c:569) io_wq_worker (io_uring/io-wq.c:?) <snip> read to 0xffff8885c4246404 of 4 bytes by task 49024 on cpu 5: io_wq_activate_free_worker (io_uring/io-wq.c:? io_uring/io-wq.c:285) io_wq_enqueue (io_uring/io-wq.c:947) io_queue_iowq (io_uring/io_uring.c:524) io_req_task_submit (io_uring/io_uring.c:1511) io_handle_tw_list (io_uring/io_uring.c:1198) <snip> Line numbers against commit 18daea77cca6 ("Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm"). These races involve writes and reads to the same memory location by different tasks running on different CPUs. To mitigate this, refactor the code to use atomic operations such as set_bit(), test_bit(), and clear_bit() instead of basic "and" and "or" operations. • https://git.kernel.org/stable/c/ab702c3483db9046bab9f40306f1a28b22dbbdc0 https://git.kernel.org/stable/c/1cbb0affb15470a9621267fe0a8568007553a4bf https://git.kernel.org/stable/c/8a565304927fbd28c9f028c492b5c1714002cbab https://access.redhat.com/security/cve/CVE-2024-39508 https://bugzilla.redhat.com/show_bug.cgi?id=2297480 • CWE-364: Signal Handler Race Condition •

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.
