Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: a potential memory leak has been fixed in mlx5einitreprx. The memory pointed to by the priv-rxres pointer is not freed during the error-prone execution of mlx5einitreprx, which can lead to a memory leak. This issue has...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fixed a potential double-free in fsanycreategroups. When kcalloc is successful for ft-g, but kvzalloc fails for in, fsanycreatetable will free ft-g. However, its caller mlx5eDestroyFlowTable will free ft-g again by...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fixed the cleanup flow for mlx5eprivinit. When mlx5eprivinit fails, the cleanup flow calls mlx5eselqcleanup, which in turn calls mlx5eselqapply. This ensures that priv-statelock is held using lockdepisheld. The statelo...
