Summary
In the Linux kernel, the following vulnerability has been resolved: usb: musb: sunxi: Fix accessing an released usb phy Commit 6ed05c68cbca ("usb: musb: sunxi: Explicitly release USB PHY on exit") will cause that usb phy @glue->xceiv is accessed after released. 1) register platform driver @sunxi_musb_driver // get the usb phy @glue->xceiv sunxi_musb_probe() -> devm_usb_get_phy(). 2) register and unregister platform driver @musb_driver musb_probe() -> sunxi_musb_init() use the phy here //the phy is released here musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy() 3) register @musb_driver again musb_probe() -> sunxi_musb_init() use the phy here but the phy has been released at 2). ... Fixed by reverting the commit, namely, removing devm_usb_put_phy() from sunxi_musb_exit().

Commit 6ed05c68cbca (\\\"usb: musb: sunxi: Liberar explícitamente USB PHY al salir\\\") provocará que se acceda al usb phy @glue->xceiv después de su liberación. 1) registrar el controlador de la plataforma @sunxi_musb_driver // obtener el usb phy @glue->xceiv sunxi_musb_probe() -> devm_usb_get_phy(). 2) registrar y anular el registro del controlador de la plataforma @musb_driver musb_probe() -> sunxi_musb_init() usa el phy aquí //el phy se publica aquí musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy() 3) registrar @musb_driver nuevamente musb_probe() -> sunxi_musb_init() usa el phy aquí pero el phy se ha publicado en 2). ... Se solucionó revirtiendo el commit, es decir, eliminando devm_usb_put_phy() de sunxi_musb_exit().\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-416\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.4.95\",\"versionEndExcluding\":\"4.5\",\"matchCriteriaId\":\"1E714DC6-1868-4774-91B0-D0274B6E3C0E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.9.59\",\"versionEndExcluding\":\"4.10\",\"matchCriteriaId\":\"D8D41D45-DE35-43A0-91F0-5FFDCB2A508A\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.13.10\",\"versionEndExcluding\":\"4.14\",\"matchCriteriaId\":\"F8E04794-8DBA-45C9-8040-A37E6BF20680\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.14\",\"versionEndExcluding\":\"4.19.324\",\"matchCriteriaId\":\"8DF05B23-9480-4E31-BE15-A93F374269CE\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.20\",\"versionEndExcluding\":\"5.4.286\",\"matchCriteriaId\":\"9952C897-8A61-4D4B-9D6D-7D063E9EA15E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.230\",\"matchCriteriaId\":\"BF5B32D0-72C9-41C3-A0BB-D4946153C134\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.172\",\"matchCriteriaId\":\"88812664-4296-42AC-AE0F-ED71086C1BB1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.1.117\",\"matchCriteriaId\":\"0DD7F755-2F6B-4707-8973-78496AD5AA8E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.2\",\"versionEndExcluding\":\"6.6.61\",\"matchCriteriaId\":\"630ED7EB-C97E-4435-B884-1E309E40D6F3\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7\",\"versionEndExcluding\":\"6.11.8\",\"matchCriteriaId\":\"0BD000F7-3DAD-4DD3-8906-98EA1EC67E95\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc1:*:*:*:*:*:*\",\"matchCriteriaId\":\"7F361E1D-580F-4A2D-A509-7615F73167A1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc2:*:*:*:*:*:*\",\"matchCriteriaId\":\"925478D0-3E3D-4E6F-ACD5-09F28D5DF82C\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc3:*:*:*:*:*:*\",\"matchCriteriaId\":\"3C95E234-D335-4B6C-96BF-E2CEBD8654ED\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc4:*:*:*:*:*:*\",\"matchCriteriaId\":\"E0F717D8-3014-4F84-8086-0124B2111379\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc5:*:*:*:*:*:*\",\"matchCriteriaId\":\"24DBE6C7-2AAE-4818-AED2-E131F153D2FA\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc6:*:*:*:*:*:*\",\"matchCriteriaId\":\"24B88717-53F5-42AA-9B72-14C707639E3F\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/498dbd9aea205db9da674994b74c7bf8e18448bd\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/4aa77d5ea9944468e16c3eed15e858fd5de44de1\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/63559ba8077cbadae1c92a65b73ea522bf377dd9\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/6e2848d1c8c0139161e69ac0a94133e90e9988e8\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/721ddad945596220c123eb6f7126729fe277ee4f\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/8a30da5aa9609663b3e05bcc91a916537f66a4cd\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/b08baa75b989cf779cbfa0969681f8ba2dc46569\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/ccd811c304d2ee
