{"id":"CVE-2026-22982","summary":"net: mscc: ocelot: Fix crash when adding interface under a lag","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mscc: ocelot: Fix crash when adding interface under a lag\n\nCommit 15faa1f67ab4 (\"lan966x: Fix crash when adding interface under a lag\")\nfixed a similar issue in the lan966x driver caused by a NULL pointer dereference.\nThe ocelot_set_aggr_pgids() function in the ocelot driver has similar logic\nand is susceptible to the same crash.\n\nThis issue specifically affects the ocelot_vsc7514.c frontend, which leaves\nunused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as\nit uses the DSA framework which registers all ports.\n\nFix this by checking if the port pointer is valid before accessing it.","modified":"2026-03-31T17:29:31.848995481Z","published":"2026-01-23T15:24:04.556Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20555-1","SUSE-SU-2026:20599-1","SUSE-SU-2026:20615-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","openSUSE-SU-2026:20287-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22982.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/03fb1708b7d1e76aecebf767ad059c319845039f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2985712dc76dfa670eb7fd607c09d4d48e5f5c6e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/34f3ff52cb9fa7dbf04f5c734fcc4cb6ed5d1a95"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8767f238b0e6c3d0b295ac6dce9fbe6a99bd1b9d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b17818307446c5a8d925a39a792261dbfa930041"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f490af47bbee02441e356a1e0b86e3b3dd5120ff"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22982.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22982"},{"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":"528d3f190c98c8f7d9581f68db4af021696727b2"},{"fixed":"8767f238b0e6c3d0b295ac6dce9fbe6a99bd1b9d"},{"fixed":"b17818307446c5a8d925a39a792261dbfa930041"},{"fixed":"2985712dc76dfa670eb7fd607c09d4d48e5f5c6e"},{"fixed":"03fb1708b7d1e76aecebf767ad059c319845039f"},{"fixed":"f490af47bbee02441e356a1e0b86e3b3dd5120ff"},{"fixed":"34f3ff52cb9fa7dbf04f5c734fcc4cb6ed5d1a95"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-22982.json"}}],"schema_version":"1.7.5"}
