Date: Wed, 6 Mar 2024 06:45:53 +0000 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2023-52595: wifi: rt2x00: restart beacon queue when hardware reset Description =========== In the Linux kernel, the following vulnerability has been resolved: wifi: rt2x00: restart beacon queue when hardware reset When a hardware reset is triggered, all registers are reset, so all queues are forced to stop in hardware interface. However, mac80211 will not automatically stop the queue. If we don't manually stop the beacon queue, the queue will be deadlocked and unable to start again. This patch fixes the issue where Apple devices cannot connect to the AP after calling ieee80211_restart_hw(). The Linux kernel CVE team has assigned CVE-2023-52595 to this issue. Affected and fixed versions =========================== Fixed in 5.4.269 with commit e1f113b57ddd Fixed in 5.10.210 with commit 69e905beca19 Fixed in 5.15.149 with commit 4cc198580a7b Fixed in 6.1.77 with commit 739b3ccd9486 Fixed in 6.6.16 with commit 04cfe4a5da57 Fixed in 6.7.4 with commit fdb580ed05df Fixed in 6.8-rc1 with commit a11d965a218f Please see https://www.kernel.org or 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-2023-52595 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/ralink/rt2x00/rt2x00dev.c drivers/net/wireless/ralink/rt2x00/rt2x00mac.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/e1f113b57ddd18274d7c83618deca25cc880bc48 https://git.kernel.org/stable/c/69e905beca193125820c201ab3db4fb0e245124e https://git.kernel.org/stable/c/4cc198580a7b93a36f5beb923f40f7ae27a3716c https://git.kernel.org/stable/c/739b3ccd9486dff04af95f9a890846d088a84957 https://git.kernel.org/stable/c/04cfe4a5da57ab9358cdfadea22bcb37324aaf83 https://git.kernel.org/stable/c/fdb580ed05df8973aa5149cafa598c64bebcd0cb https://git.kernel.org/stable/c/a11d965a218f0cd95b13fe44d0bcd8a20ce134a8
