{"apiVersion":"1.0","identifier":"CVE-2026-72004","description":"In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix memory leak in ieee80211_register_hw() If kmemdup() fails while copying supported band structures, the error path jumps to fail_rate. This skips rate_control_deinitialize() and leaks the initialized local->rate_ctrl. Fix this by adding a fail_band label that shares the rate-control cleanup path before falling through to the remaining teardown. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1-rc7. An x86_64 allyesconfig build showed no new warnings. As we do not have a suitable mac80211 device/driver combination to test with, no runtime testing was able to be performed.","publishedAt":"2026-08-15T06:20:58","lastModifiedAt":"2026-08-17T06:17:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72004","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00211,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72004","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72004","en":"https://www.redsauce.net/en/cves/CVE-2026-72004","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72004","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72004","de":"https://www.redsauce.net/de/cves/CVE-2026-72004","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72004","el":"https://www.redsauce.net/el/cves/CVE-2026-72004"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72004"}}
