kernel: out-of-bounds write in index_rbio_pages in fs/btrfs/raid56.c
In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image can lead to slab-out-of-bounds write access in index_rbio_pages in fs/btrfs/raid56.c.
A flaw was found in the BTRFS implementation in the Linux kernel. A slab-out-of-bounds write occurs when an attacker can mount a specially crafted BTRFS disk or disk image.
Statement: This issue is considered as having Low impact because it needs physical access to trigger and it's also in Technology Preview functionality. For more information regarding BTRFS support in Red Hat Enterprise Linux 6 and 7 refer to https://access.redhat.com/solutions/197643 .
Mitigation: As the BTRFS module will be auto-loaded when required, its use can be disabled by preventing the mo

CVE-2019-19378 [HIGH] CVE-2019-19378 kernel: out-of-bounds write in index_rbio_pages in fs/btrfs/raid56.c
CVE-2019-19378 kernel: out-of-bounds write in index_rbio_pages in fs/btrfs/raid56.c
A flaw was found in the Linux kernels BTRFS implementation which could allow for a slab-out-of-bounds write when an attacker is able to mount a specifically crafted BTRFS disk or disk image.
The attacker must create an image with unexpected values to convince the kernel to write disk metadata information in the wrong location.
This could allow for memory corruption or possibly privilege escalation.
