In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix FRMR set pinned push error path Add destruction of FRMR handles… (CVE-2026-74298)
A vulnerability in the Linux kernel RDMA core related to FRMR handle management has been resolved. The issue involved a failure to properly destroy FRMR handles when a push to the pool failed, which could lead to resource leaks. This fix prevents such leaks by ensuring proper cleanup in error paths.
AI Analysis
Technical Summary
The Linux kernel RDMA core had a vulnerability (CVE-2026-74298) where the failure path for setting pinned push in FRMR did not destroy FRMR handles, causing resource leaks if pool page allocation failed. The patch adds destruction of these handles in the error path to prevent resource leakage.
Potential Impact
The vulnerability could cause resource leaks in the kernel when pool page allocation fails during FRMR set pinned push operations. This may degrade system stability or performance but does not indicate direct code execution or privilege escalation from the provided data.
Mitigation Recommendations
A fix has been applied to the Linux kernel to address this issue. Users should update to the patched kernel version once available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory or Linux kernel release notes for the official fix and version details.
