CVE-2026-46178 Details
Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx4: Fix resource leak on error in mlx4_ib_create_srq() Sashiko points out that mlx4_srq_alloc() was not undone during error unwind, add the missing call to mlx4_srq_free().
A resource leak vulnerability has been identified in the Linux kernel's RDMA mlx4 component, specifically within the srq.c file. The issue arises in the 'mlx4_ib_create_srq()' function, where the 'mlx4_srq_alloc()' allocation is not properly released during error handling. This oversight can lead to memory leaks by failing to free allocated resources when an error occurs.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
