Taking the lock again inside the DSA wrappers causes a deadlock.\n\nStumbled upon this when booting qemu with fbnic and CONFIG_NET_DSA_LOOP=y\n(which looks like some kind of testing device that auto-populates the ports\nof eth0). `ethtool -i` is enough to deadlock. This means we have basically zero\ncoverage for DSA stuff with real ops locked devs.\n\nRemove the redundant netdev_lock_ops()/netdev_unlock_ops() calls from\nthe DSA conduit ethtool wrappers.","published_at":"2026-06-26T19:41:13.926000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/74d64ae4254e99ef8c8215b057a76edac82c5f99","https://git.kernel.org/stable/c/abe91fd045874d21834482adcd7a9693e7377056","https://git.kernel.org/stable/c/0f99e0c3e19badaf3fdced0d3feba623e59eed41"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:28.590503Z","updated_at":"2026-06-28T23:30:52.348775Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.15","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.15"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.15","version_start_inclusive":true,"version_end":"6.15","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.15:6.15"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2bcf4772e45adb00649a4e9cbff14b08a144f9e3","version_start_inclusive":true,"version_end":"74d64ae4254e99ef8c8215b057a76edac82c5f99","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2bcf4772e45adb00649a4e9cbff14b08a144f9e3:74d64ae4254e99ef8c8215b057a76edac82c5f99"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2bcf4772e45adb00649a4e9cbff14b08a144f9e3","version_start_inclusive":true,"version_end":"abe91fd045874d21834482adcd7a9693e7377056","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2bcf4772e45adb00649a4e9cbff14b08a144f9e3:abe91fd045874d21834482adcd7a9693e7377056"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2bcf4772e45adb00649a4e9cbff14b08a144f9e3","version_start_inclusive":true,"version_end":"0f99e0c3e19badaf3fdced0d3feba623e59eed41","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2bcf4772e45adb00649a4e9cbff14b08a144f9e3:0f99e0c3e19badaf3fdced0d3feba623e59eed41"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.18.33","version_start_inclusive":true,"version_end":"6.18.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.18.33:6.18.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.0.10","version_start_inclusive":true,"version_end":"7.0.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.0.10:7.0.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.1","version_start_inclusive":true,"version_end":"*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.1:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://git.kernel.org/stable/c/74d64ae4254e99ef8c8215b057a76edac82c5f99","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/abe91fd045874d21834482adcd7a9693e7377056","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/0f99e0c3e19badaf3fdced0d3feba623e59eed41","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-26T19:41:13.926000Z","label":"CVE published","source":null}]}
