Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a security issue in net/mlx5...

kernel: net/mlx5e: Prevent deadlock while disabling aRFS

A flaw was found in the Linus Kernel. A potential deadlock can occur while disabling aRFS in drivers/net/ethernet/mellanox/mlx5/core/enarfs.c...

SUSE CVE-2023-52851

In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Fix init stage error handling to avoid double free of same QP and UAF In the unlikely event that workqueue allocation fails and returns NULL in mlx5mkeycacheinit, delete the call to mlx5rumrresourcecleanup which frees th...

SUSE CVE-2021-47438

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix memory leak in mlx5coredestroycq error path Prior to this patch in case mlx5coredestroycq failed it returns without completing all destroy operations and that leads to memory leak. Instead, complete the destroy flo...

CVE-2021-47261

In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Fix initializing CQ fragments buffer The function initcqfragbuf can be called to initialize the current CQ fragments buffer cq-buf, or the temporary cq-resizebuf that is filled during CQ resize operation. However, the...

CVE-2021-47481

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Initialize the ODP xarray when creating an ODP MR Normally the zero fill would hide the missing initialization, but an errant set to descsize in regcreate causes a crash: BUG: unable to handle page fault for address:...

SUSE CVE-2021-47246

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix page reclaim for dead peer hairpin When adding a hairpin flow, a firmware-side send queue is created for the peer net device, which claims some host memory pages for its internal ring buffer. If the peer net device...

SUSE CVE-2021-47265

In the Linux kernel, the following vulnerability has been resolved: RDMA: Verify port when creating flow rule Validate port value provided by the user and with that remove no longer needed validation by the driver. The missing check in the mlx5ib driver could cause to the below oops. Call trace:...

CVE-2021-47481

CVE-2021-47481 concerns the Linux kernel RDMA mlx5 path. The connected sources confirm a concrete flaw where the ODP xarray was not initialized when creating an ODP MR, allowing an out-of-bounds/invalid access that triggers a crash (page fault) due to reg_create() setting a desc_size. The fix des...
