UBUNTU-CVE-2025-22062: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: What access would an attacker need to trigger this issue?

The reported crash occurs through the proc/sysctl handler for SCTP UDP port configuration. The supplied severity vector indicates local access, low privileges, no user interaction, and that the attack conditions are present.

Q: What is the likely impact if the issue is exploited?

The vulnerability can cause a kernel crash through a race between SCTP UDP socket stop and start operations. The severity vector indicates an availability impact on the vulnerable system, with no indicated confidentiality or integrity impact.

Q: Which Ubuntu kernel packages are identified as affected?

The listed software includes ubuntu/linux-realtime, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-azure-fde, ubuntu/linux-gke, ubuntu/linux-gkeop, ubuntu/linux-riscv, and ubuntu/linux-aws-fips.
