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...

CVE-2026-74664 net: openvswitch: reallocate update replies for mismatched IDs

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: reallocate update replies for mismatched IDs ovsflowcmdnew preallocates the optional reply skb before it takes ovsmutex and before it knows which existing flow will be updated. That is normally fine because the...

CVE-2026-74626

CVE-2026-74626 affects the Linux kernel's Non-Transparent Bridge (NTB) virtual ethernet driver (ntb_netdev). The root cause is in ntb_netdev_rx_handler(), which hands the received skb to the network stack before allocating its replacement. When the allocation fails, the buffer is not reposted, so...

CVE-2026-74602

CVE-2026-74602 is a Linux kernel vulnerability in the ring-buffer subsystem. In rb_allocate_cpu_buffer(), the field bpage->order was left uninitialized (defaulting to 0). This becomes a problem when a ring-buffer uses subbuffers larger than PAGE_SIZE, because free_buffer_page() relies on the c...

SUSE CVE-2026-63384

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an incorrect integer conversion in eventtagging.c when evtagunmarshalheader uses evtagdecodeint to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INTMAX becom...
