CVE-2026-43126

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: mixer: oss: Add card disconnect checkpoints<br /> <br /> ALSA OSS mixer layer calls the kcontrol ops rather individually, and<br /> pending calls might be not always caught at disconnecting the device.<br /> <br /> For avoiding the potential UAF scenarios, add sanity checks of the<br /> card disconnection at each entry point of OSS mixer accesses. The<br /> rwsem is taken just before that check, hence the rest context should<br /> be covered by that properly.
