GHSA-R635-G3XR-VW7X Socket.IO: Engine.IO Polling Transport Connection Exhaustion

Impact An unauthenticated remote attacker can cause a denial of service in affected versions of engine.io by opening Engine.IO polling sessions and sending an invalid binary POST request with: Content-Type: application/octet-stream against an Engine.IO protocol v4 polling transport. In the...

CVE-2026-64055 net: ethernet: cortina: Carry over frag counter

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Carry over frag counter The gmacrx NAPI poll function assembles packets in an SKB from a ring buffer. If the ring buffer gets completely emptied during a poll cycle, we exit gmacrx, but the packet is not y...

Open Event Server through 1.19.1 contains a missing authentication vulnerability that allows unauthenticated attackers to export the complete member roster of any group, including email addresses, names, join dates, and roles, by submitting requests to the group followers CSV export endpoint whic...

PYSEC-2026-3033 python-engineio has possible denial of service due to maximum payload size sometimes not being enforced

Impact There are two specific configurations of the python-engineio server in which the size of incoming messages is not checked before the messages are loaded into memory. An attacker can take advantage of these to cause unnecessary memory allocations in the python-engineio server. The two cases...
