CVE-2024-53148
7.8 · HIGHOverview
CVE-2024-53148 is a high-severity vulnerability affecting linux linux_kernel. It was published on December 24, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:
comedi: Flush partial mappings in error case
If some remap_pfn_range() calls succeeded before one failed, we still have
buffer pages mapped into the userspace page tables when we drop the buffer
reference with comedi_buf_map_put(bm). The userspace mappings are only
cleaned up later in the mmap error path.
Fix it by explicitly flushing all mappings in our VMA on the error path.
See commit 79a61cc3fc04 ("mm: avoid leaving partial pfn mappings around in
error case").
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.
