{"id":"CVE-2026-98705","published":"2026-10-18T16:17:24.017","lastModified":"2026-10-19T10:19:34.800","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: account proxy paths against the mesh path limit\n\nProxy-path churn can drive the interface path counter negative and let\nlater mesh path additions exceed MESH_MAX_MPATHS.\n\nmesh_path_free_rcu() decrements the interface mpaths counter for entries\nfrom both the mesh and proxy path tables, but mpp_path_add() never\nreserves a slot in that counter. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3b75831ceee76d32bb8e7ddd241904f92f9b5407","tags":[]},{"url":"https://git.kernel.org/stable/c/5a32409ed34a1868830899a5d2437f0b3bf3532c","tags":[]},{"url":"https://git.kernel.org/stable/c/a5f35d4b112af1415ff06bd501c8cc26cc08aa8b","tags":[]},{"url":"https://git.kernel.org/stable/c/df072db65fdaa34ad15e1d66fc06a53e3e97f778","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
