5.5 · MEDIUMOverview
CVE-2024-26839 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 17, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix a memleak in init_credit_return
When dma_alloc_coherent fails to allocate dd->cr_base[i].va,
init_credit_return should deallocate dd->cr_base and
dd->cr_base[i] that allocated before. Or those resources
would be never freed and a memleak is triggered.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
