No remote or adjacent peer can drive `.get_txpower`.\nAC:L - There is no race, no memory-grooming requirement, and no attacker-uncontrollable condition; the attacker simply issues the request and can poll indefinitely until a wireless vif is in the not-in-driver state, which is the persistent default on rfkill'd/Wi-Fi-off systems, on created-but-unstarted vifs, and on every vif after a hw-restart reconfig failure.\nPR:L - A plain unprivileged local account suffices — `NL80211_CMD_GET_INTERFACE` is explicitly marked in the nl80211 ops table as retrievable by unprivileged users (no `GENL_ADMIN_PERM`), and `wext_permission_check()` requires `CAP_NET_ADMIN` only for SET ioctls, leaving `SIOCGIWTXPOW` open to anyone.\nUI:N - The attacker triggers the bug entirely on their own by running `iw dev` or `iwconfig`; no action by any other user or administrator is needed at the time of exploitation.\nS:U - The uninitialized/stale dereference happens in kernel driver code and its consequences stay within the kernel's own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - On all pre-6.11 affected branches `vif->drv_priv` is never cleared after `remove_interface()`, so the driver dereferences pointers to freed objects — a use-after-free read whose result is additionally returned to userspace as the tx-power value via `NL80211_ATTR_WIPHY_TX_POWER_LEVEL`/`iwconfig`, leaking kernel memory contents.\nI:H - Driver `.get_txpower` handlers operate on the stale private area (dereferencing freed pointers, taking locks and walking driver structures through them), and a use-after-free on attacker-reclaimable heap memory is leverageable for controlled writes and control-flow influence, so integrity impact is scored High.\nA:H - Dereferencing uninitialized or freed driver private data reliably oopses the kernel — the fix's own rationale is \"avoid potentially crashing in the driver because of uninitialized private data\" — and any unprivileged user can retrigger it at will."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/mac80211/cfg.c"],"versions":[{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"b0b862aa3dbcd16b3c4715259a825f48ca540088","status":"affected","versionType":"git"},{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"78b698fbf37208ee921ee4cedea75b5d33d6ea9f","status":"affected","versionType":"git"},{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"c21efba8b5a86537ccdf43f77536bad02f82776c","status":"affected","versionType":"git"},{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"b2bcbe5450b20641f512d6b26c6b256a5a4f847f","status":"affected","versionType":"git"},{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"8f6cd4d5bb7406656835a90e4f1a2192607f0c21","status":"affected","versionType":"git"},{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"ee35c423042c9e04079fdee3db545135d609d6ea","status":"affected","versionType":"git"},{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"3ccf525a73d48e814634847f6d4a6150c6f0dffc","status":"affected","versionType":"git"},{"version":"5b3dc42b1b0db0264bbbe4ae44c15ab97bfd1e93","lessThan":"393b6bc174b0dd21bb2a36c13b36e62fc3474a23","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/cfg.c"],"versions":[{"version":"3.19","status":"affected"},{"version":"0","lessThan":"3.19","status":"unaffected","versionType":"semver"},{"version":"4.19.323","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.285","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.229","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.171","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.116","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.60","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.11.7","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","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":"3.19","versionEndExcluding":"4.19.323"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.4.285"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.10.229"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.15.171"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.1.116"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.6.60"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.11.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b0b862aa3dbcd16b3c4715259a825f48ca540088"},{"url":"https://git.kernel.org/stable/c/78b698fbf37208ee921ee4cedea75b5d33d6ea9f"},{"url":"https://git.kernel.org/stable/c/c21efba8b5a86537ccdf43f77536bad02f82776c"},{"url":"https://git.kernel.org/stable/c/b2bcbe5450b20641f512d6b26c6b256a5a4f847f"},{"url":"https://git.kernel.org/stable/c/8f6cd4d5bb7406656835a90e4f1a2192607f0c21"},{"url":"https://git.kernel.org/stable/c/ee35c423042c9e04079fdee3db545135d609d6ea"},{"url":"https://git.kernel.org/stable/c/3ccf525a73d48e814634847f6d4a6150c6f0dffc"},{"url":"https://git.kernel.org/stable/c/393b6bc174b0dd21bb2a36c13b36e62fc3474a23"}],"title":"wifi:
