{"id":"CVE-2026-98381","summary":"veth: manage XDP program pointers during channel resize","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nveth: manage XDP program pointers during channel resize\n\nveth_set_channels() tears down XDP resources for removed RX queues\nwithout clearing rq-\u003exdp_prog.  If the program is then detached or\nreplaced, those queues keep the old pointer after bpf_prog_put().\nA later channel increase can re-enable NAPI and run the freed program.\n\n  BUG: unable to handle page fault for address: ffffc90000256048\n  Oops: Oops: 0000 [#1] SMP KASAN NOPTI\n  RIP: veth_xdp_rcv_skb (include/linux/filter.h:779\n                         include/net/xdp.h:696 drivers/net/veth.c:820)\n  Call Trace:\n   veth_xdp_rcv (drivers/net/veth.c:941)\n   veth_poll (drivers/net/veth.c:986)\n   __napi_poll (net/core/dev.c:7787)\n   net_rx_action (net/core/dev.c:7850 net/core/dev.c:8007)\n   handle_softirqs (kernel/softirq.c:645)\n  Kernel panic - not syncing: Fatal exception in interrupt","modified":"2026-10-10T02:47:33.078279383Z","published":"2026-10-09T07:34:21.029Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98381.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1a5c5b9c64ba5f39dba55da6e12561ca56eeb758"},{"type":"WEB","url":"https://git.kernel.org/stable/c/25bb7c36225220d30f404d7e29d2e052bc5f4b99"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3c10a5dd0d38f506f671dbb59e9d0ee4c72076f9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/43f6b647f209591b1e3f726bb16b8dcba6b95908"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7104a370714346b667712913dc16abf14bbc97ed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a8e143109ff2736dc79e41dcd55af7ceab7520a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f0e8dba8c224981e53c792c6b3dbb7604fb2c2c6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98381.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98381"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4752eeb3d891c27905a8fdf4d80e899c0efd4ec7"},{"fixed":"7a8e143109ff2736dc79e41dcd55af7ceab7520a"},{"fixed":"1a5c5b9c64ba5f39dba55da6e12561ca56eeb758"},{"fixed":"f0e8dba8c224981e53c792c6b3dbb7604fb2c2c6"},{"fixed":"3c10a5dd0d38f506f671dbb59e9d0ee4c72076f9"},{"fixed":"25bb7c36225220d30f404d7e29d2e052bc5f4b99"},{"fixed":"43f6b647f209591b1e3f726bb16b8dcba6b95908"},{"fixed":"7104a370714346b667712913dc16abf14bbc97ed"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98381.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98381.json"}}],"schema_version":"1.9.0"}
