CVE-2026-74510

CVE-2026-74510 affects the Linux kernel Bluetooth mgmt subsystem. It describes a use-after-free (UAF) in pair command cancellation: pairing completion and authentication failure callbacks could dereference a command freed due to races on the shared mgmt_pending list. The root cause is a lookup th...

CVE-2026-74393

In the Linux kernel, the following vulnerability has been resolved: drm/syncobj: Fix memory leak in drmsyncobjfindfence Commit 18226ba52159 "drm/syncobj: reject invalid flags in drmsyncobjfindfence" forgot to take into account the fact that drmsyncobjfind takes a reference to syncobj and returns...

CVE-2026-68477

In the Linux kernel, the following vulnerability has been resolved: ipvs: fix more places with wrong ipv6 transport offsets Sashiko reports for more incorrect IPv6 transport offsets. The app code for TCP was assuming IPv4 network header even after the ipvsh argument was provided. This can cause...

CVE-2026-68474

In the Linux kernel, the following vulnerability has been resolved: powerpc/spufs: fix out-of-bounds access in spufsmemmmapaccess spufsmemmmapaccess computes the local store offset as address - vma-vmstart, but bounds-checks it against vma-vmend instead of the local store size. On 64-bit, offset ...

CVE-2026-68418

A flaw was found in the RDMA/irdma component of the Linux kernel. A local user could exploit this vulnerability by providing a zero value for userwqebufs during the creation of a Queue Pair QP. This action leads to a null pointer dereference, which can cause the system to crash, resulting in a...

CVE-2026-68417

A flaw was found in the Linux kernel's RDMA/siw component. The siwcreateqp function prematurely publishes a Queue Pair QP before its complete initialization. This allows a Queue Pair Number QPN lookup to access a QP that is still under construction, potentially leading to unexpected behavior or...

CVE-2026-68418

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent user-triggered null deref on QP create Previously, the user QP creation path would only attempt to populate iwqp-iwpbl if the user-provided req.userwqebufs field was non-zero. The problem is that iwqp-iwpbl is...

CVE-2026-68417

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siwcreateqp currently calls siwqpadd before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being...

CVE-2026-68422

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix root leak if its reloc root is unexpected in mergerelocroots If we have an unexpected relocroot for our root, we jump to the out label but never drop the reference we obtained for root, resulting in a leak. Add a missi...

EUVD-2026-55604

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent user-triggered null deref on QP create Previously, the user QP creation path would only attempt to populate iwqp-iwpbl if the user-provided req.userwqebufs field was non-zero. The problem is that iwqp-iwpbl is...

CVE-2026-68418

CVE-2026-68418 affects the Linux kernel RDMA/irdma path, specifically QP creation. The root cause was that iwqp->iwpbl could be dereferenced unconditionally later in irdma_setup_virt_qp if a user supplied req.user_wqe_bufs, even when it was zero. Although there was a NULL check, it only applie...

CVE-2026-68417 RDMA/siw: publish QP after initialization

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siwcreateqp currently calls siwqpadd before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being...

CVE-2026-68417

The CVE-2026-68417 issue affects the Linux kernel RDMA/siw component. Root cause: siw_create_qp() calls siw_qp_add() before QP state/queues/CQs/completion/device list are fully initialized, allowing a QPN lookup to reach a QP still under construction. The remediation implemented in the public des...
