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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/mac80211/mesh_pathtbl.c"],"versions":[{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"0e79c9d260862bd4676955d3cac7baa0d38a5b2e","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"bfd447ee32f727e535e317aa5a8447488f943803","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"7f83dab0045f756a82a15ac751165aefa03bed11","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"c66ab4b94bb04c162485759196555e08c0965320","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"df072db65fdaa34ad15e1d66fc06a53e3e97f778","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"3b75831ceee76d32bb8e7ddd241904f92f9b5407","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"5a32409ed34a1868830899a5d2437f0b3bf3532c","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"a5f35d4b112af1415ff06bd501c8cc26cc08aa8b","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/mac80211/mesh_pathtbl.c"],"versions":[{"version":"3.2","status":"affected"},{"version":"0","lessThan":"3.2","status":"unaffected","versionType":"semver"},{"version":"5.10.273","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.224","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.191","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"5.10.273"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"5.15.224"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.1.191"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.6.160"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.12.113"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.18.56"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"7.2.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0e79c9d260862bd4676955d3cac7baa0d38a5b2e"},{"url":"https://git.kernel.org/stable/c/bfd447ee32f727e535e317aa5a8447488f943803"},{"url":"https://git.kernel.org/stable/c/7f83dab0045f756a82a15ac751165aefa03bed11"},{"url":"https://git.kernel.org/stable/c/c66ab4b94bb04c162485759196555e08c0965320"},{"url":"https://git.kernel.org/stable/c/df072db65fdaa34ad15e1d66fc06a53e3e97f778"},{"url":"https://git.kernel.org/stable/c/3b75831ceee76d32bb8e7ddd241904f92f9b5407"},{"url":"https://git.kernel.org/stable/c/5a32409ed34a1868830899a5d2437f0b3bf3532c"},{"url":"https://git.kernel.org/stable/c/a5f35d4b112af1415ff06bd501c8cc26cc08aa8b"}],"title":"wifi: mac80211: account proxy paths against the mesh path limit","x_generator":{"engine":"bippy-1.2.0"}}}}
