CVE-2026-93110

CVE-2026-93110 affects the Linux kernel 's RDMA/core subsystem, specifically the ib_core module. The vulnerability arises because put_gid_ndev() is queued via call_rcu(), but stopping workqueues during module unload does not drain already-queued RCU callbacks. Since synchronize_rcu() does not wai...

CVE-2026-92512

A use-after-free vulnerability in the Linux kernel RDMA/core subsystem affects the ib_query_qp() function. When a QP is queried via the netlink resource tracking flow, the only synchronization is rdma_restrack_get() , but on the destroy path, rdma_restrack_del() is called too late—after vendor-sp...

CVE-2026-92511

This Linux kernel vulnerability affects the RDMA/core subsystem, specifically the ib_destroy_cq_user() function. The root cause is that rdma_restrack_del() is invoked at the end of the function, after vendor-specific resources associated with the Completion Queue (CQ) have already been freed. Thi...

CVE-2026-92510

CVE-2026-92510 affects the Linux kernel RDMA/core subsystem. The vulnerable function is ib_destroy_srq_user() , where a use-after-free can occur when a Shared Receive Queue (SRQ) is accessed via the netlink path. The root cause is that rdma_restrack_del() is invoked at the end of the destruction ...

CVE-2026-92509

CVE-2026-92509 is a potential use-after-free in the Linux kernel RDMA/core subsystem, specifically in the counter_release() function. The root cause is a timing issue: rdma_restrack_del() was invoked at the end of counter_release(), after vendor-specific resources had already been freed. This lef...

CVE-2026-92508

CVE-2026-92508 is a use-after-free vulnerability in the Linux kernel's RDMA/core subsystem, specifically in the ib_free_cq() function. The root cause is that rdma_restrack_del() is invoked at the end of the CQ destruction sequence, after vendor-specific resources have already been freed. This cre...

CVE-2026-92507

CVE-2026-92507 is a use-after-free in the Linux kernel's RDMA/core subsystem, specifically in the ib_dealloc_pd_user() function. When a Protection Domain (PD) is accessed via the netlink path, the only synchronization mechanism is rdma_restrack_get(). The vulnerability arises because rdma_restrac...

CVE-2026-74299

A flaw was found in the Linux kernel's RDMA/core component. When aging pools with pinned handles, a failure to move handles from the active queue to an inactive queue during new page allocation can lead to a memory leak. This occurs because the system does not properly handle the fault, resulting...
