{"id":"CVE-2026-99048","summary":"gve: fix napi_disable deadlock when attempting to disable XSK pools","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngve: fix napi_disable deadlock when attempting to disable XSK pools\n\nWhen disabling XSK pools, GVE calls the unlocked versions of\nnapi_disable and napi_enable. However, the netdev lock has already been\nacquired before ndo_bpf is called because GVE supports queue management\nops. Calling the unlocked versions of napi_disable/enable results in a\ndeadlock when attempting to disable XSK pools, as the thread attempts to\nre-acquire a lock it already holds.\n\nUpdate the NAPI calls to use the locked versions.\n\nThis issue was found in production.","modified":"2026-10-25T02:47:29.870756684Z","published":"2026-10-23T12:22:13.825Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99048.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0cb6939a4dfefa822007b7a71986e06bc4f61f54"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3d377911ce81fd4e61af814e750d8e08879a5208"},{"type":"WEB","url":"https://git.kernel.org/stable/c/42935a61001927aa01db10b53b420efd37eaa99b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99048.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99048"},{"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":"606048cbd8346e616cfaee01b0143d072534136d"},{"fixed":"42935a61001927aa01db10b53b420efd37eaa99b"},{"fixed":"3d377911ce81fd4e61af814e750d8e08879a5208"},{"fixed":"0cb6939a4dfefa822007b7a71986e06bc4f61f54"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99048.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.57"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99048.json"}}],"schema_version":"1.9.2"}
