CVE-2023-5369 (GCVE-0-2023-5369)

Vulnerability from cvelistv5 – Published: 2023-10-04 03:48 – Updated: 2025-02-13 17:20

Title

copy_file_range insufficient capability rights check

Summary

Before correction, the copy_file_range system call checked only for the CAP_READ and CAP_WRITE capabilities on the input and output file descriptors, respectively. Using an offset is logically equivalent to seeking, and the system call must additionally require the CAP_SEEK capability. This incorrect privilege check enabled sandboxed processes with only read or write but no seek capability on a file descriptor to read data from or write data to an arbitrary location within the file corresponding to that file descriptor.

Severity
