{"id":"CVE-2026-53157","summary":"net: phonet: free phonet_device after RCU grace period","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: phonet: free phonet_device after RCU grace period\n\nphonet_device_destroy() removes a phonet_device from the per-net device\nlist with list_del_rcu(), but frees it immediately. RCU readers walking\nthe same list can still hold a pointer to the object after it has been\nremoved, leading to a slab-use-after-free.\n\nUse kfree_rcu(), matching the lifetime rule already used by\nphonet_address_del() for the same object type.","modified":"2026-07-09T04:44:19.911586400Z","published":"2026-06-25T08:38:40.132Z","related":["CGA-9pcc-x3h5-mrmh"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53157.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09c9b92c2010481160245244ea8fa1d06d5d4ae0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ec8011cce0cd0fc7a5068585d867fc08d508578"},{"type":"WEB","url":"https://git.kernel.org/stable/c/52b8f5ef82c886f7cd24617915e4b1579ddfd001"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6cd7067d6e4b0b2033ba2f918ecbd54dc2af3763"},{"type":"WEB","url":"https://git.kernel.org/stable/c/71de0177b28da751f407581a4515cf4d762f6296"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bd2ab4d800fc26814d89328d87b5f97ef6aa906a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bff309ea51f1395c1ef8be8b75ce62d28a319113"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d59794337ea496042288c7c68356d9b9ca7f46a9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53157.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53157"},{"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":"eeb74a9d45f781ec6f47b9e0a75a6a427b53f165"},{"fixed":"d59794337ea496042288c7c68356d9b9ca7f46a9"},{"fixed":"6cd7067d6e4b0b2033ba2f918ecbd54dc2af3763"},{"fixed":"2ec8011cce0cd0fc7a5068585d867fc08d508578"},{"fixed":"09c9b92c2010481160245244ea8fa1d06d5d4ae0"},{"fixed":"bd2ab4d800fc26814d89328d87b5f97ef6aa906a"},{"fixed":"52b8f5ef82c886f7cd24617915e4b1579ddfd001"},{"fixed":"bff309ea51f1395c1ef8be8b75ce62d28a319113"},{"fixed":"71de0177b28da751f407581a4515cf4d762f6296"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53157.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.33"},{"fixed":"5.10.260"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.211"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.177"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.144"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.95"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53157.json"}}],"schema_version":"1.7.5"}
