1) Out-of-bounds read (CVE-ID: CVE-2026-80779)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause memory corruption.

The vulnerability exists due to an out-of-bounds read in the Ionic network driver RX queue initialization logic when initializing a dedicated hardware timestamp receive queue. A local user can trigger XDP_TX processing on the affected receive queue to cause memory corruption.

The dedicated hardware timestamp receive queue does not have a corresponding normal transmit queue partner.
