CVE-2026-31493

The CVE-2026-31493 issue exists in Linux kernel RDMA/efa admin queue completion handling: when a command completes with an error, the code may print from a completion context that has already been freed, leading to use-after-free-like behavior. The root cause is use of a freed completion context ...

CVE-2026-31493 RDMA/efa: Fix use of completion ctx after free

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix use of completion ctx after free On admin queue completion handling, if the admin command completed with error we print data from the completion context. The issue is that we already freed the completion context in...

CVE-2026-31492

The CVE-2026-31492 entry concerns the Linux kernel RDMA irdma driver. Root cause: in irdma_create_qp, if ib_copy_to_udata fails, irdma_destroy_qp cleanup waits on free_qp completion that has not been initialized yet. The fix is to initialize the free_qp completion before the ib_copy_to_udata call...

CVE-2026-31492 RDMA/irdma: Initialize free_qp completion before using it

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Initialize freeqp completion before using it In irdmacreateqp, if ibcopytoudata fails, it will call irdmadestroyqp to clean up which will attempt to wait on the freeqp completion, which is not initialized yet. Fix thi...

CVE-2026-31467

CVE-2026-31467 concerns the Linux kernel vulnerability where the bio completion path in certain process contexts (e.g., dm-verity) could call into decompression and then into vm_map_ram() with GFP_KERNEL, risking memory pressure and a potential deadlock in submit_bio_wait. The issue is tied to th...

CVE-2026-31436

Summary of CVE-2026-31436 : The Linux kernel’s dmaengine idxd driver contains a bug in the llist_abort_desc() function where the code completes the wrong descriptor (the variable “found” rather than the traversal cursor “d”) as the function unwinds a doubly linked list. This can lead to NULL poin...
