CVE-2024-53148

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the Linux kernel and involves a problem with partial mappings in the error case for the comedi subsystem. If some remap pfn range() calls succeed before one fails, buffer pages remain mapped into the userspace page tables when the buffer reference is dropped with comedi buf map put(bm). These mappings are only cleaned up later in the mmap error path. The fix involves explicitly flushing all mappings in the VMA on the error path.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
