  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ndrm/imagination: Fix deadlock in soft reset sequence\nThe soft reset sequence is currently executed from the threaded IRQ\nhandler, hence it cannot call disable_irq() which internally waits\nfor IRQ handlers, i.e. itself, to complete.\nUse disable_irq_nosync() during a soft reset instead.", "A flaw was found in the Linux kernel's `drm/imagination` driver. A local attacker could potentially trigger a deadlock condition during the soft reset sequence. This occurs because the soft reset sequence, when executed from a threaded Interrupt Request (IRQ) handler, attempts to disable IRQs while waiting for itself to complete. This can lead to a system hang or unresponsiveness, resulting in a Denial of Service (DoS)." ],
