CVE-2015-0275 [MEDIUM] kernel: fs: ext4: fallocate zero range page size > block size BUG()
kernel: fs: ext4: fallocate zero range page size > block size BUG()
The ext4_zero_range function in fs/ext4/extents.c in the Linux kernel before 4.1 allows local users to cause a denial of service (BUG) via a crafted fallocate zero-range request.
A flaw was found in the way the Linux kernel's ext4 file system handled the "page size > block size" condition when the fallocate zero range functionality was used. A local attacker could use this flaw to crash the system.
Statement: This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 and 6. This issue does affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 7 and Red Hat Enterprise MRG 2. Future updates in the respective releases may address this issue.
