CVE-2026-80779

CVE-2026-80779 is a Linux kernel vulnerability in the net/ionic network driver. The dedicated hardware timestamp RX queue is allocated with an index equal to nrxqs_per_lif , but the txqcqs array only holds regular queue pairs. Using that out-of-bounds index to set rxq->partner can read one ent...

CVE-2026-80779: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net/ionic: avoid OOB TX partner lookup for hwstamp RXQ The dedicated hardware timestamp RX queue is allocated with q-index equal to lif-ionic-nrxqsperlif. The normal txqcqs array only contains the regular queue pairs, so using th...
