https://notcve.org/view.php?id=CVE-2024-42071
In the Linux kernel, the following vulnerability has been resolved: ionic: use dev_consume_skb_any outside of napi If we're not in a NAPI softirq context, we need to be careful about how we call napi_consume_skb(), specifically we need to call it with budget==0 to signal to it that we're not in a safe context. This was found while running some configuration stress testing of traffic and a change queue config loop running, and this curious note popped out: [ 4371.402645] BUG: using smp_processor_id() in preemptible [00000000] code: ethtool/20545 [ 4371.402897] caller is napi_skb_cache_put+0x16/0x80 [ 4371.403120] CPU: 25 PID: 20545 Comm: ethtool Kdump: loaded Tainted: G OE 6.10.0-rc3-netnext+ #8 [ 4371.403302] Hardware name: HPE ProLiant DL360 Gen10/ProLiant DL360 Gen10, BIOS U32 01/23/2021 [ 4371.403460] Call Trace: [ 4371.403613] <TASK> [ 4371.403758] dump_stack_lvl+0x4f/0x70 [ 4371.403904] check_preemption_disabled+0xc1/0xe0 [ 4371.404051] napi_skb_cache_put+0x16/0x80 [ 4371.404199] ionic_tx_clean+0x18a/0x240 [ionic] [ 4371.404354] ionic_tx_cq_service+0xc4/0x200 [ionic] [ 4371.404505] ionic_tx_flush+0x15/0x70 [ionic] [ 4371.404653] ? ionic_lif_qcq_deinit.isra.23+0x5b/0x70 [ionic] [ 4371.404805] ionic_txrx_deinit+0x71/0x190 [ionic] [ 4371.404956] ionic_reconfigure_queues+0x5f5/0xff0 [ionic] [ 4371.405111] ionic_set_ringparam+0x2e8/0x3e0 [ionic] [ 4371.405265] ethnl_set_rings+0x1f1/0x300 [ 4371.405418] ethnl_default_set_doit+0xbb/0x160 [ 4371.405571] genl_family_rcv_msg_doit+0xff/0x130 [...] I found that ionic_tx_clean() calls napi_consume_skb() which calls napi_skb_cache_put(), but before that last call is the note /* Zero budget indicate non-NAPI context called us, like netpoll */ and DEBUG_NET_WARN_ON_ONCE(!in_softirq()); Those are pretty big hints that we're doing it wrong. We can pass a context hint down through the calls to let ionic_tx_clean() know what we're doing so it can call napi_consume_skb() correctly. • https://git.kernel.org/stable/c/386e69865311044b576ff536c99c6ee9cc98a228 https://git.kernel.org/stable/c/ef7646ed49fff962e97b276f4ab91327a67eeb5a https://git.kernel.org/stable/c/84b767f9e34fdb143c09e66a2a20722fc2921821 •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42070 – netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers
https://notcve.org/view.php?id=CVE-2024-42070
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers register store validation for NFT_DATA_VALUE is conditional, however, the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This only requires a new helper function to infer the register type from the set datatype so this conditional check can be removed. Otherwise, pointer to chain object can be leaked through the registers. This vulnerability allows local attackers to disclose sensitive information on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the implementation of packet filtering. • https://git.kernel.org/stable/c/96518518cc417bb0a8c80b9fb736202e28acdf96 https://git.kernel.org/stable/c/40188a25a9847dbeb7ec67517174a835a677752f https://git.kernel.org/stable/c/23752737c6a618e994f9a310ec2568881a6b49c4 https://git.kernel.org/stable/c/5d43d789b57943720dca4181a05f6477362b94cf https://git.kernel.org/stable/c/461302e07f49687ffe7d105fa0a330c07c7646d8 https://git.kernel.org/stable/c/efb27ad05949403848f487823b597ed67060e007 https://git.kernel.org/stable/c/952bf8df222599baadbd4f838a49c4fef81d2564 https://git.kernel.org/stable/c/41a6375d48deaf7f730304b5153848bfa • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix possible double free in error handling path When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), callback function adev_release calls kfree(madev).
