Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: Fixed a memory leak in skbSegmentList for GRO packets When skbSegmentList is called during packet forwarding, it handles packets that were aggregated by the GRO engine. Historically, the segmentation logic in skbSegmentList...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bnxten: Avoid order-5 memory allocation for TPA data. The driver needs to keep track of all possible concurrent TPA GRO/LRO completions on the aggregation ring. On P5 chips, the maximum number of concurrent TPA is 256, and the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: UDP: Do not accept non-tunnel GSO packets that land in a tunnel. When rx-udp-gro-forwarding is enabled, UDP packets may be forwarded in a way that causes them to land in a tunnel. This can lead to various issues. udpgroreceive...
