- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix exclusive map memory leak
When exclproghash is 0 and exclproghash_size is non-zero, the map also needs to be freed. Otherwise, the map memory will not be reclaimed, just like the memory leak problem reported by syzbot [1].
syzbot reported: BUG: memory leak backtrace (crc 7b9fb9b4): map_create+0x322/0x11e0 kernel/bpf/syscall.c:1512 _sysbpf+0x3556/0x3610 kernel/bpf/syscall.c:6131
