https://notcve.org/view.php?id=CVE-2025-38200
04 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: i40e: fix MMIO write access to an invalid page in i40e_clear_hw When the device sends a specific input, an integer underflow can occur, leading to MMIO write access to an invalid page. Prevent the integer underflow by changing the type of related variables. In the Linux kernel, the following vulnerability has been resolved: i40e: fix MMIO write access to an invalid page in i40e_clear_hw When the device sends a specific input, an integer und... • https://git.kernel.org/stable/c/1bff652941c4d94f97610c9a30473aad6f5b2fff •

CVE-2025-38194 – jffs2: check that raw node were preallocated before writing summary

04 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: jffs2: check that raw node were preallocated before writing summary Syzkaller detected a kernel bug in jffs2_link_node_ref, caused by fault injection in jffs2_prealloc_raw_node_refs. jffs2_sum_write_sumnode doesn't check return value of jffs2_prealloc_raw_node_refs and simply lets any error propagate into jffs2_sum_write_data, which eventually calls jffs2_link_node_ref in order to link the summary to an expectedly allocated node. kernel BUG... • https://git.kernel.org/stable/c/2f785402f39b96a077b6e62bf26164bfb8e0c980 •

CVE-2025-38190 – atm: Revert atm_account_tx() if copy_from_iter_full() fails.
https://notcve.org/view.php?id=CVE-2025-38190
04 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: atm: Revert atm_account_tx() if copy_from_iter_full() fails. In vcc_sendmsg(), we account skb->truesize to sk->sk_wmem_alloc by atm_account_tx(). It is expected to be reverted by atm_pop_raw() later called by vcc->dev->ops->send(vcc, skb). However, vcc_sendmsg() misses the same revert when copy_from_iter_full() fails, and then we will leak a socket. Let's factorise the revert part as atm_return_tx() and call it in the failure path. • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 •

CVE-2025-38185 – atm: atmtcp: Free invalid length skb in atmtcp_c_send().

04 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: atm: atmtcp: Free invalid length skb in atmtcp_c_send(). syzbot reported the splat below. [0] vcc_sendmsg() copies data passed from userspace to skb and passes it to vcc->dev->ops->send(). atmtcp_c_send() accesses skb->data as struct atmtcp_hdr after checking if skb->len is 0, but it's not enough. Also, when skb->len == 0, skb and sk (vcc) were leaked because dev_kfree_skb() is not called and sk_wmem_alloc adjustment is missing to revert at... • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 •

CVE-2025-38177 – sch_hfsc: make hfsc_qlen_notify() idempotent
https://notcve.org/view.php?id=CVE-2025-38177
04 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: sch_hfsc: make hfsc_qlen_notify() idempotent hfsc_qlen_notify() is not idempotent either and not friendly to its callers, like fq_codel_dequeue(). Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers' life: 1. update_vf() decreases cl->cl_nactive, so we can check whether it is non-zero before calling it. 2. eltree_remove() always removes RB node cl->el_node, but we can use RB_EMPTY_NODE() + RB_CLEAR_NODE() to make it safe.
