Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Add a timeout to acquire the command queue semaphore Prevent forced completion handling on an entry that has not yet been assigned an index, causing an out of bounds access on idx = -22. Instead of waiting indefinitely for the sem, blocking flow now waits for index to be allocated or a sem acquisition timeout before beginning the timer for FW completion. Kernel log example: mlx5_core 0000:06:00.0: wait_func_handle_exec_timeout:1128:(pid 185911): cmd[-22]: CREATE_UCTX(0xa04) No done completion

The reported trigger (CREATE_UCTX from a userspace pid) is a local ioctl path.\nAC:L - The attacker controls both sides: they flood the command interface to keep all max_reg_cmds slots occupied (a saturation mode mlx5 maintainers explicitly documented for unprivileged/high-rate command issuers) while issuing the victim blocking command that parks on the semaphore, and each resulting timeout permanently leaks a slot, making the exhausted-semaphore state self-reinforcing and eventually deterministic.\nPR:L - An unprivileged local user with access to /dev/infiniband/uverbs* (mode 0666 under stock rdma-core udev rules on RDMA-enabled hosts) can issue the exact CREATE_UCTX command from the report via ALLOC_UCONTEXT with MLX5_IB_ALLOC_UCTX_DEVX, with no capability check on that path.\nUI:N - Exploitation requires only the attacker\u0027s own syscalls/ioctls against the RDMA device; no action by any other user or administrator is needed.\nS:U - The use-after-free and its consequences are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed mlx5_cmd_work_ent is reused by the still-parked work handler, which reads ent-\u003ein/ent-\u003eout/ent-\u003euout pointers out of reclaimed heap memory and copies FW output through them, giving an attacker who sprays the freed slot a read primitive into kernel memory.\nI:H - The parked handler writes ent-\u003eidx, ent-\u003elay and ent-\u003ets1 into freed memory, installs a dangling pointer in cmd-\u003eent_arr[] that a later FW completion dereferences to call ent-\u003ecallback(err, context) \u2014 a function pointer taken from sprayable freed memory \u2014 and programs DMA addresses read from freed memory into the NIC command descriptor before ringing the doorbell.\nA:H - The bug produces stuck commands, permanently leaked command-queue slots that eventually wedge the entire firmware command interface (rendering the NIC unconfigurable), plus a use-after-free that reliably causes oops/panic even when not fully exploited."
