Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix for a variable not being completed when the function returns When cmdallocindex fails, cmdworkhandler needs to complete ent-slotted before returning early. Otherwise, the task that issued the command may hang...

CVE-2026-74712

A flaw was found in the Linux kernel's vdpa/mlx5 driver. This vulnerability occurs due to an incorrect calculation of buffer length within the createdirectkeys function, causing the system to read beyond its allocated memory boundaries. A local attacker could exploit this memory corruption to...

CVE-2026-72345

A flaw was found in the Linux kernel's mlx5 LAG Link Aggregation Group driver. An off-by-one error in the mlx5lagcreatesinglefdb function's error rollback mechanism can lead to operations on uninitialized memory or a double-free condition. This could result in system instability or a denial of...

CVE-2026-72341

A flaw was found in the Linux kernel's net/mlx5e component. A local attacker could exploit a race condition during the publication of channel statistics. On weakly-ordered architectures, this could lead to a null pointer dereference, causing a system crash and a denial of service...

Linux Distros Unpatched Vulnerability : CVE-2026-74297

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - RDMA/mlx5: Fix undefined shift of user RQ WQE size setrqsize computes the RQ WQE size as 1 rqwqeshift based on the user-provided rqwqeshift, which is only check...

CVE-2026-72006

A flaw was found in the Linux kernel's mlx5 driver. Repeated allocation and release of mkeys with TPH steering-tag hints can cause a memory leak of struct mlx5stidxdata. This unreferenced memory accumulates over time, potentially leading to resource exhaustion and a Denial of Service DoS for...

The vulnerability of the functions mlx5e_tc_del_fdb_peer_flow() and mlx5e_tc_clean_fdb_peer_flows() in the driver module drivers/net/ethernet/mellanox/mlx5/core/en_tc.c of the Mellanox Ethernet network adapter driver for the Linux operating system, which allows a hacker to cause a service failure.

The vulnerability of the functions mlx5etcdelfdbpeerflow and mlx5etccleanfdbpeerflows in the driver module drivers/net/ethernet/mellanox/mlx5/core/entc.c of the Mellanox Ethernet network adapter driver for the Linux operating system is related to the use of pointers.
