UBUNTU-CVE-2026-99046

In the Linux kernel, the following vulnerability has been resolved: gve: fix XSK buffer leak on error descriptor When the error bit is set in the RX completion descriptor, the bufstate and its attached buffer should be freed. In the case of AFXDP ZC, the XSK buffer was not freed, leading to a lea...

UBUNTU-CVE-2026-99047

In the Linux kernel, the following vulnerability has been resolved: gve: fix XSK buffer leak when rings are stopped GVE does not free XSK buffers when resetting ring state as a part of stopping queues. This causes all XSK buffers which are posted to the NIC to be leaked. Free XSK buffers attached...
