{"id":"CVE-2026-97973","summary":"net: macb: destroy the phylink instance on the probe error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: macb: destroy the phylink instance on the probe error path\n\nmacb_mii_init() creates a phylink instance on both of its success paths,\nbut the probe unwind frees the netdev without destroying it, so a failing\nmacb_alloc_tieoff() or register_netdev() leaks the instance.\n\nDestroy it at err_out_unregister_mdio, which is only reachable once\nmacb_mii_init() has succeeded, so bp-\u003ephylink is valid there.","modified":"2026-10-09T17:26:54.163588307Z","published":"2026-09-25T10:23:12.759Z","related":["openSUSE-SU-2026:12074-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97973.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0112aa02c7847314be599d68783d50c7e228a694"},{"type":"WEB","url":"https://git.kernel.org/stable/c/23b6a44ffea1c54a4232aa86ee470b21422a8cc5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d059f390750152b9bd69df934198651b94fc26d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8558e3195664113c14a4d8fcf221b3caff41fed1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c1de1e7b51ab2531f564b39b51998c3d71caccd7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e92a45b872b035c79acde8dd0da096a72b61ff2f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97973.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97973"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7897b071ac3b45a5788d084fc7f8a8ee9e5f07f0"},{"fixed":"0112aa02c7847314be599d68783d50c7e228a694"},{"fixed":"c1de1e7b51ab2531f564b39b51998c3d71caccd7"},{"fixed":"23b6a44ffea1c54a4232aa86ee470b21422a8cc5"},{"fixed":"e92a45b872b035c79acde8dd0da096a72b61ff2f"},{"fixed":"8558e3195664113c14a4d8fcf221b3caff41fed1"},{"fixed":"7d059f390750152b9bd69df934198651b94fc26d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97973.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97973.json"}}],"schema_version":"1.9.0"}
