In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix inversion dependency warning while enabling IPsec tunnel Attempt to enable IPsec packet offload in tunnel mode in debug kernel generates the following kernel panic, which is happening due to two issues: 1. In SA ad...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: vfio: Split migration operations from main device operations The vfio core checks whether the driver sets certain migration operations e.g., setstate/getstate, and accordingly calls those operations. However, currently, the ml...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Avoid unregistering PSP twice. PSP is unregistered twice in the following paths: mlx5eremove - mlx5epspunregister mlx5eniccleanup - mlx5epspunregister This leads to a refcount underflow under certain conditions:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mlx5: Fixed a leak in skb during fifo resync and push operations. During the ptp resync operation, SKBs were popped from the fifo, but they were never freed either by napiconsume or by devkfreeskbany. Added a call to...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Unregisters devlink parameters in case the interface is down Currently, if an interface is down, the mlx5 driver does not unregister its devlink parameters, which leads to this WARN1. This issue is fixed by unregisterin...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Register devlink first under the devlink lock. If the device encounters a non-fatal firmware error during the probe, the driver will report the error to the user via devlink. This will trigger a WARN, since mlx5 calls...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: RX, Fix XDP multi-buf frag counting for striding RQ XDP multi-buf programs can modify the layout of the XDP buffer when the program calls bpfxdppulldata or bpfxdpadjusttail. The referenced commit in the fixes tag...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fixed the rollback of the switchdev mode in case of failure. If for some internal reason the switchdev mode fails, we roll back to the legacy mode. Before this patch, rolling back would unregister the uplink netdev and...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mlx5: fixed the potential use-of-free situation during the use of PTP queue FIFO. FIFO indexes are not checked during pop operations, which can lead to a use-of-free issue when popping items from an empty queue. This issue was...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Take the RTNL lock when necessary before calling xdpsetfeatures. The RTNL lock should be held when calling xdpsetfeatures with a registered netdev, as this call triggers the netdev notifiers. This could occur, for...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net/mlx5: HWS, fixed the issue where complex rule rehash operations failed. Moving rules from one matcher to another should not fail. However, if it does fail due to various reasons, the error handling mechanism should allow t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: LAG, fixed the logic for MLX5LAGFLAGNDEVSREADY Set MLX5LAGFLAGNDEVSREADY only if both devices are registered. This ensures that both ldev-pfMLX5LAGP0.dev and ldev-pfMLX5LAGP1.dev have valid pointers when...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Data related to command failures should only be collected for known commands. DEVX can issue a general command, which is not used by the mlx5 driver. If such a command fails, mlx5 attempts to collect the failure data...
