Hi Team, I found the way to mitigate the above stack -- in cups/dest.c in static int cups_enum_dests( ..) where you return() add free(data.devices) as you data.devices point to the allocated memory by cupsArrayNew3(..) which we need to free
Found the memory leak in libcups.so.2, following is the stack from the valgrind, Any fix is available for Rocky 8 ?
==1065== 789,696 bytes in 3,656 blocks are definitely lost in loss record 18,029 of 18,033 ==1065== at 0x4C3CE4B: calloc (vg_replace_malloc.c:1328) ==1065== by 0x4B6A5FA4: cupsArrayNew3 (in /usr/lib64/libcups.so.2) ==1065== by 0x4B6ABD02: ???
