Message-ID: <2025072533-CVE-2025-38406-5f5c@gregkh> Date: Fri, 25 Jul 2025 15:13:34 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...nel.org> Subject: CVE-2025-38406: wifi: ath6kl: remove WARN on bad firmware input From: Greg Kroah-Hartman <gregkh@...nel.org> Description =========== In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: remove WARN on bad firmware input If the firmware gives bad input, that's nothing to do with the driver's stack at this point etc., so the WARN_ON() doesn't add any value. Additionally, this is one of the top syzbot reports now. Just print a message, and as an added bonus, print the sizes too. The Linux kernel CVE team has assigned CVE-2025-38406 to this issue. Affected and fixed versions =========================== Fixed in 5.4.296 with commit 7a2afdc5af3b82b601f6a2f0d1c90d5f0bc27aeb Fixed in 5.10.240 with commit e6c49f0b203a987c306676d241066451b74db1a5 Fixed in 5.15.187 with commit 46b47d4b06fa7f234d93f0f8ac43798feafcff89 Fixed in 6.1.144 with commit 89bd133529a4d2d68287128b357e49adc00ec690 Fixed in 6.6.97 with commit 347827bd0c5680dac2dd59674616840c4d5154f1 Fixed in 6.12.37 with commit 327997afbb5e62532c28c1861ab5534c01969c9a Fixed in 6.15.6 with commit 27d07deea35ae67f2e75913242e25bdb7e1114e5 Fixed in 6.16-rc3 with commit e7417421d89358da071fd2930f91e67c7128fbff Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2025-38406 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ath6kl/bmi.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7a2afdc5af3b82b601f6a2f0d1c90d5f0bc27aeb https://git.kernel.org/stable/c/e6c49f0b203a987c306676d241066451b74db1a5 https://git.kernel.org/stable/c/46b47d4b06fa7f234d93f0f8ac43798feafcff89 https://git.kernel.org/stable/c/89bd133529a4d2d68287128b357e49adc00ec690 https://git.kernel.org/stable/c/347827bd0c5680dac2dd59674616840c4d5154f1 https://git.kernel.org/stable/c/327997afbb5e62532c28c1861ab5534c01969c9a https://git.kernel.org/stable/c/27d07deea35ae67f2e75913242e25bdb7e1114e5 https://git.kernel.org/stable/c/e7417421d89358da071fd2930f91e67c7128fbff
