Linux kernel Btrfs Heap Buffer Overflow DoS

The vulnerability of the functions btrfssplitdelallocextent and btrfsmergedelallocextent in the fs/btrfs/inode.c module of the file system in Linux operating systems is related to the execution of operations outside of the buffer memory. Exploitation of this vulnerability could allow an attacker ...

Linux kernel Heap Buffer Overflow DoS

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...
