Removing or expiring a proxy path\ntherefore returns a slot that was never charged.\n\nmesh_path_add() uses the same counter to enforce MESH_MAX_MPATHS, so once\nit falls below the number of installed paths the limit no longer holds.\n\nReserve the shared quota before allocating a proxy path and release it on\nevery unsuccessful addition. Mesh and proxy paths now share one\n1024-entry budget, so mpp_path_add() can return -ENOSPC at that limit.","score":null,"severity":"unknown","published":"2026-10-18T15:46:35.520Z","modified":"2026-10-30T12:38:55.966Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"0e79c9d260862bd4676955d3cac7baa0d38a5b2e","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"bfd447ee32f727e535e317aa5a8447488f943803","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"7f83dab0045f756a82a15ac751165aefa03bed11","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"c66ab4b94bb04c162485759196555e08c0965320","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"df072db65fdaa34ad15e1d66fc06a53e3e97f778","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"3b75831ceee76d32bb8e7ddd241904f92f9b5407","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"5a32409ed34a1868830899a5d2437f0b3bf3532c","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","status":"affected","lessThan":"a5f35d4b112af1415ff06bd501c8cc26cc08aa8b","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98705"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"3.2","status":"affected"},{"version":"0","status":"unaffected","lessThan":"3.2","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.113","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.56","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.10","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98705"}],"remediation":[],"references":["https://git.kernel.org/stable/c/0e79c9d260862bd4676955d3cac7baa0d38a5b2e","https://git.kernel.org/stable/c/bfd447ee32f727e535e317aa5a8447488f943803","https://git.kernel.org/stable/c/7f83dab0045f756a82a15ac751165aefa03bed11","https://git.kernel.org/stable/c/c66ab4b94bb04c162485759196555e08c0965320","https://git.kernel.org/stable/c/df072db65fdaa34ad15e1d66fc06a53e3e97f778","https://git.kernel.org/stable/c/3b75831ceee76d32bb8e7ddd241904f92f9b5407","https://git.kernel.org/stable/c/5a32409ed34a1868830899a5d2437f0b3bf3532c","https://git.kernel.org/stable/c/a5f35d4b112af1415ff06bd501c8cc26cc08aa8b"],"sources":[{"name":"CVE","id":"CVE-2026-98705","modified":"2026-10-30T12:38:55.966Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98705"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:02:34.368Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:35:33.875Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
