The vulnerability of the iomap_write_delalloc_scan() function in the fs/iomap/buffered-io.c module of the Linux kernel file system allows a attacker to cause a service failure.

The vulnerability of the iomapwritedelallocscan function in the fs/iomap/buffered-io.c file of the Linux kernel file system is related to copying buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability could allow an attacker to cause a...
