CVE-2026-80863 RDMA/rxe: Fix OOB in free_rd_atomic_resources()

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix OOB in freerdatomicresources freerdatomicresources iterates using qp-attr.maxdestrdatomic. Updating maxdestrdatomic before freeing the old array can make the free path walk past the old allocation and trigger a slab...

CVE-2026-80863

CVE-2026-80863 is a slab out-of-bounds write (size 4) in the Linux kernel's RDMA/rxe (Soft-RoCE) driver, specifically in free_rd_atomic_resources() at drivers/infiniband/sw/rxe/rxe_qp.c. The root cause is that max_dest_rd_atomic is updated before the old array is freed, causing the free path to i...

CVE-2026-80862

This Linux kernel vulnerability affects the nvme-tcp subsystem. The page_frag_cache is used to preallocate PDU buffers for preallocated block device requests, but since block devices are created in parallel threads, the cache is accessed in a thread-unsafe manner. This leads to incorrect refcount...

CVE-2026-80861

CVE-2026-80861 is a vulnerability in the Linux kernel xHCI USB host controller driver (specifically the xhci-pci-renesas path). The root cause is in xhci_gen_setup(): when a USB controller (e.g., Renesas uPD720201 ) is dead or has dropped off the bus, the capability register read returns all-ones...
