CVE-2026-31491

A flaw was found in the Linux kernel's RDMA/irdma component. A local attacker could exploit an integer overflow and truncation vulnerability when the operating system passes a maximum unsigned 32-bit integer U32MAX for SQ/RQ/SRQ size. This can lead to the system incorrectly reporting a successful...

CVE-2026-31493

A flaw was found in the Linux kernel's RDMA/efa component. When an admin command completes with an error during admin queue completion handling, the system attempts to print data from a completion context that has already been freed. This use-after-free vulnerability can lead to the disclosure of...
