CVE-2026-74397

CVE-2026-74397 affects the Linux kernel mlx5 driver (IB/mlx5). The issue arises in mlx5_ib_alloc_transport_domain() which can leak a transport domain if mlx5_ib_enable_lb() fails; a fix deallocates the TD on error, returns 0 explicitly in the no-loopback-capability success branch, and moves dev-&...

CVE-2026-74397 IB/mlx5: Fix transport-domain rollback and initialize lb mutex earlier

In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Fix transport-domain rollback and initialize lb mutex earlier mlx5iballoctransportdomain allocates a transport domain and then may fail in mlx5ibenablelb. In that case, the allocated TD is leaked. Fix this by deallocatin...

CVE-2026-74396

CVE-2026-74396 affects the Linux kernel in the RDMA/mlx5 stack. The issue occurs in the path that allocates and DMA maps an XLT buffer via mlx5r_umr_create_xlt() and releases it through mlx5r_umr_unmap_free_xlt(). If mlx5_odp_populate_xlt() encounters an error, its error path previously returned ...
