{"id":"CVE-2026-98494","summary":"net: atl1: fix soft lockup on out-of-range cmb_tpd_next_to_clean read","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: atl1: fix soft lockup on out-of-range cmb_tpd_next_to_clean read\n\nSame issue as atl1c (see the first commit in this series, \"net:\natl1c: fix soft lockup on out-of-range tpd_cons read\"): the hardware\ncan report an out-of-range cmb_tpd_next_to_clean (seen as 0xffff)\nwhile the PCIe link/MAC is resetting. An out-of-range value can\nnever be reached and the loop below would spin forever. Treat it as\n\"nothing new to clean\" instead.","modified":"2026-10-20T02:30:14.747899649Z","published":"2026-10-18T15:16:23.155Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98494.json","cna_assigner":"Linux"},"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/0f573b0576252d44fb27ab8470ea873bc6408ef3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/43e746821f5f5afbbf68e388bf9fbe221e03bfca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d7ac337d37cb97d77e4c910d37746694b606661"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6285919d4c06254d257d24dc980f6332e1984a82"},{"type":"WEB","url":"https://git.kernel.org/stable/c/632cd7b81cb7bab36112f02eb2ee7f7cc1214fb1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ab9f61ca851f02ae4398cebaf00735a22e1d6ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79e2447b11322c27ef9ac423be0a94efc7691f02"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c55e51d5899e80f9593b26985ed0b89e0c828a5e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98494.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98494"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f3cc28c797604fa1cda4aef3f250f465de54a0ca"},{"fixed":"5d7ac337d37cb97d77e4c910d37746694b606661"},{"fixed":"c55e51d5899e80f9593b26985ed0b89e0c828a5e"},{"fixed":"6ab9f61ca851f02ae4398cebaf00735a22e1d6ca"},{"fixed":"632cd7b81cb7bab36112f02eb2ee7f7cc1214fb1"},{"fixed":"79e2447b11322c27ef9ac423be0a94efc7691f02"},{"fixed":"0f573b0576252d44fb27ab8470ea873bc6408ef3"},{"fixed":"6285919d4c06254d257d24dc980f6332e1984a82"},{"fixed":"43e746821f5f5afbbf68e388bf9fbe221e03bfca"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98494.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.21"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"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-2026-98494.json"}}],"schema_version":"1.9.0"}
