A malformed image can make the\nregion table pointer precede the firmware buffer, make the record loop\nfail to advance, or index phy->clc past its end. Validate the table and\nrecord bounds before dereferencing or copying.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
