Description
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix potential memory leak in ext4_fc_record_regions()
As krealloc may return NULL, in this case 'state->fc_regions' may not be
freed by krealloc, but 'state->fc_regions' already set NULL. Then will
lead to 'state->fc_regions' memory leak.
Affected configurations
• linux linux kernel (>= 5.10 < 5.10.150)
• linux linux kernel (>= 5.11 < 5.15.75)
• linux linux kernel (>= 5.16 < 5.19.17)
• linux linux kernel (>= 6.0 < 6.0.3)
