CVE-2026-74652

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> serial: amba-pl011: cancel RS485 hrtimers after freeing IRQ<br /> <br /> The RS485 trigger hrtimers are embedded in the devm-managed port and can<br /> fire after it is freed. The IRQ handler can arm a timer, so free the IRQ<br /> first and then cancel both timers.<br /> <br /> Complete the RS485 stop without arming a timer, and cancel the timers<br /> in remove() for the suspend-then-unbind path, where shutdown is not<br /> called.<br /> <br /> This issue was found by an in-house static analysis tool.
