It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-48652 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-48652/ (Markdown: https://insights.sbomify.com/CVE-2022-48652/index.md)","id":"CVE-2022-48652","markdown":"https://insights.sbomify.com/CVE-2022-48652/index.md","name":"CVE-2022-48652","record":{"aliases":["DEBIAN-CVE-2022-48652","GHSA-4j53-q2r4-27jv","UBUNTU-CVE-2022-48652"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A local attacker can cause a kernel crash in the Intel ice driver by triggering a null pointer dereference during Traffic Class updates.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nice: Fix crash by keep old cfg when update TCs more than queues\n\nThere are problems if allocated queues less than Traffic Classes.\n\nCommit a632b2a4c920 (\"ice: ethtool: Prohibit improper channel config\nfor DCB\") already disallow setting less queues than TCs.\n\nAnother case is if we first set less queues, and later update more TCs\nconfig due to LLDP, ice_vsi_cfg_tc() will failed but left dirty\nnum_txq/rxq and tc_cfg in vsi, that will cause invalid pointer access.\n\n[   95.968089] ice 0000:3b:00.1: More TCs defined than queues/rings allocated.\n[   95.968092] ice 0000:3b:00.1: Trying to use more Rx queues (8), than were allocated (1)!\n[   95.968093] ice 0000:3b:00.1: Failed to config TC for VSI index: 0\n[   95.969621] general protection fault: 0000 [#1] SMP NOPTI\n[   95.969705] CPU: 1 PID: 58405 Comm: lldpad Kdump: loaded Tainted: G     U  W  O     --------- -t - 4.18.0 #1\n[   95.969867] Hardware name: O.E.M/BC11SPSCB10, BIOS 8.23 12/30/2021\n[   95.969992] RIP: 0010:devm_kmalloc+0xa/0x60\n[   95.970052] Code: 5c ff ff ff 31 c0 5b 5d 41 5c c3 b8 f4 ff ff ff eb f4 0f 1f 40 00 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 48 89 f8 89 d1 \u003c8b\u003e 97 60 02 00 00 48 8d 7e 18 48 39 f7 72 3f 55 89 ce 53 48 8b 4c\n[   95.970344] RSP: 0018:ffffc9003f553888 EFLAGS: 00010206\n[   95.970425] RAX: dead000000000200 RBX: ffffea003c425b00 RCX: 00000000006080c0\n[   95.970536] RDX: 00000000006080c0 RSI: 0000000000000200 RDI: dead000000000200\n[   95.970648] RBP: dead000000000200 R08: 00000000000463c0 R09: ffff888ffa900000\n[   95.970760] R10: 0000000000000000 R11: 0000000000000002 R12: ffff888ff6b40100\n[   95.970870] R13: ffff888ff6a55018 R14: 0000000000000000 R15: ffff888ff6a55460\n[   95.970981] FS:  00007f51b7d24700(0000) GS:ffff88903ee80000(0000) knlGS:0000000000000000\n[   95.971108] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[   95.971197] CR2: 00007fac5410d710 CR3: 0000000f2c1de002 CR4: 00000000007606e0\n[   95.971309] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[   95.971419] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[   95.971530] PKRU: 55555554\n[   95.971573] Call Trace:\n[   95.971622]  ice_setup_rx_ring+0x39/0x110 [ice]\n[   95.971695]  ice_vsi_setup_rx_rings+0x54/0x90 [ice]\n[   95.971774]  ice_vsi_open+0x25/0x120 [ice]\n[   95.971843]  ice_open_internal+0xb8/0x1f0 [ice]\n[   95.971919]  ice_ena_vsi+0x4f/0xd0 [ice]\n[   95.971987]  ice_dcb_ena_dis_vsi.constprop.5+0x29/0x90 [ice]\n[   95.972082]  ice_pf_dcb_cfg+0x29a/0x380 [ice]\n[   95.972154]  ice_dcbnl_setets+0x174/0x1b0 [ice]\n[   95.972220]  dcbnl_ieee_set+0x89/0x230\n[   95.972279]  ?
