CVE-2026-31769

The CVE-2026-31769 issue in the Linux kernel gpib module is resolved by adding a kernel-only descriptor_busy reference count in struct gpib_descriptor to prevent use-after-free of gpib_descriptor objects during concurrent IO ioctl handling (IBRD, IBWRT, IBCMD, IBWAIT). Each IO path increments des...
