CVE-2026-80859

CVE-2026-80859 affects the Linux kernel FUSE (Filesystem in Userspace) subsystem. The root cause is a missing read memory barrier (smp_rmb()) in fuse_block_alloc(). The function reads fch->initialized followed by fch->io_uring, but lacks the barrier needed to pair with the smp_wmb() in fuse...

In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: put CQ ref on createcq mapping failure nvmetpciepfcreatecq calls nvmetcqcreate, which takes a reference on the controller and installs the completion queue. If the subsequent PCI address-space mapping fails or...

CVE-2026-80770

CVE-2026-80770 affects the Linux kernel Nintendo HID driver (Joy-Con). In nintendo_hid_probe(), when joycon_init() or joycon_leds_create() fails after hid_device_io_start(), the error path calls hid_hw_close()/hid_hw_stop() without first calling hid_device_io_stop(). Since hid_hw_stop() does not ...
