"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: arm_scmi: Avoid IDR updates while cleaning channels\n\nscmi_cleanup_channels() walks the TX/RX channel IDRs with\nidr_for_each() to free transport resources and destroy the dedicated\ntransport devices before calling idr_destroy().\n\nThe destroy callback removed each entry from the same IDR being walked.\nThat is not needed for this cleanup path, and it is unsafe because\nidr_for_each() has not advanced its radix-tree iterator while the\ncallback is running. Removing the current entry from the callback can\ninvalidate the iterator state. The callback also cannot be protected by\nrcu_read_lock(), because scmi_device_destroy() may sleep.\n\nLeave IDR teardown to the following idr_destroy() call and keep the\ncallback limited to device destruction."
