CVE-2026-74728

CVE-2026-74728 is a NULL pointer dereference in the Linux kernel's XFS filesystem repair tooling. When xfs_buf_alloc_backing_mem() fails, xfs_buf_free() is called with bp->b_addr still NULL. The code then falls through to the folio_put path, which calls virt_to_folio(NULL), dereferencing an in...

CVE-2026-74713

A flaw in the Linux kernel's vhost_iotlb module allows non-retiring IOTLB tables to continue allocating entries beyond their configured limit (default 2048 for vhost devices). A local attacker or a malicious guest operating system can trigger a continuous stream of IOTLB updates, causing unbounde...

CVE-2026-74706 bnge: Fix NULL pointer dereference in aux device release

In the Linux kernel, the following vulnerability has been resolved: bnge: Fix NULL pointer dereference in aux device release If allocation of auxrdev fails during auxiliary device setup, the error path calls auxiliarydeviceuninit, which eventually invokes bngeauxdevrelease. The release callback...

CVE-2026-74706

CVE-2026-74706 is a NULL pointer dereference in the Linux kernel's bnge (Broadcom NetXtreme-E) network driver. When allocation of auxr_dev fails during auxiliary device setup, the error path invokes bnge_aux_dev_release(), which unconditionally dereferences aux_priv->auxr_dev->pdev. Since a...
