UBUNTU-CVE-2024-56748: Medium severity ubuntu/linux-azure vulnerability

Q: What access does an attacker need to exploit this issue?

The vulnerability has local attack vector and requires low privileges. No user interaction is required.

Q: What is the practical impact of successful exploitation?

The stated impact is availability only: a failure path can leak DMA-coherent memory during qedf status-block initialization. Confidentiality and integrity impacts are not indicated.

Q: Which Ubuntu kernel packages are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-azure, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-gcp-fips, ubuntu/linux-gcp, and ubuntu/linux-oracle.

Published Dec 29, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: scsi: qedf: Fix a possible memory leak in qedfallocandinitsb() Hook "qedops->common->sbinit = qedsbinit" does not release the DMA memory sbvirt when it fails. Add dmafreecoherent() to free it. This is the same way as qedrallocmemsb() and qedeallocmemsb().
