Vulnerability from cvelistv5
Published

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: IB/mlx5: Fix transport-domain rollback and initialize lb mutex earlier mlx5_ib_alloc_transport_domain() allocates a transport domain and then may fail in mlx5_ib_enable_lb(). In that case, the allocated TD is leaked. Fix this by deallocating the TD when mlx5_ib_enable_lb() returns an error. Also return 0 explicitly in the no-loopback-capability success branch, and move dev->lb.mutex initialization to mlx5_ib_stage_init_init().

alloc_ucontext and create_qp require no real root/CAP_SYS_ADMIN, only local access to the mlx5 RDMA character device on hosts with the hardware.\\nUI:N - Exploitation needs only attacker-driven ibverbs calls; no victim interaction such as mounting filesystems, clicking links, or opening files is required.\\nS:U - Impact stays within the host kernel mlx5 RDMA driver scope; this is not a VM escape, IOMMU/DMA boundary bypass, or other cross-security-authority compromise per kernel CVSS guidance.\\nC:H - Locking an uninitialized dev-\u003elb.mutex in mlx5_ib_enable_lb()/disable_lb is undefined behavior that can corrupt kernel memory and be leveraged for arbitrary kernel memory disclosure.\\nI:H - Uninitialized mutex use during ucontext transport-domain setup or raw-packet QP creation can corrupt adjacent kernel structures and enable arbitrary write or control-flow hijack primitives.\\nA:H - Invalid mutex operations can kernel panic/oops; repeated alloc_ucontext without TD rollback on mlx5_ib_enable_lb() failure exhausts transport domains and denies further RDMA context/QP creation (DoS).\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"146d2f1af3245a10b13eef263687e54f4e253d1d\", \"lessThan\": \"2c3b2667dad69d56774b79db763acb3a1bee0fc0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"146d2f1af3245a10b13eef263687e54f4e253d1d\", \"lessThan\": \"37fc3cc0f924fd8d0f0cf87b92672dec75a32e57\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"146d2f1af3245a10b13eef263687e54f4e253d1d\", \"lessThan\": \"65e344925fa30abf50c8de8c150b397715fa2066\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"146d2f1af3245a10b13eef263687e54f4e253d1d\", \"lessThan\": \"f88e12c95fc19f719e06ca1e9eb20fdad68ef61a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"146d2f1af3245a10b13eef263687e54f4e253d1d\", \"lessThan\": \"e79389115b9d27287ff6230a9750675106ed7668\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/infiniband/hw/mlx5/main.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.5\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.5\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.145\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.97\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.40\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/infiniband/hw/mlx5/main.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/2c3b2667dad69d56774b79db763acb3a1bee0fc0\"}, {\"url\": \"https://git.kernel.org/stable/c/37fc3cc0f924fd8d0f0cf87b92672dec75a32e57\"}, {\"url\": \"https://git.kernel.org/stable/c/65e344925fa30abf50c8de8c150b397715fa2066\"}, {\"url\": \"https://git.kernel.org/stable/c/f88e12c95fc19f719e06ca1e9eb20fdad68ef61a\"}, {\"url\": \"https://git.kernel.org/stable/c/e79389115b9d27287ff6230a9750675106ed7668\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nIB/mlx5: Fix transport-domain rollback and initialize lb mutex earlier\\n\\nmlx5_ib_alloc_transport_domain() allocates a transport domain and then\\nmay fail in mlx5_ib_enable_lb().
