CVE-2018-10880
Published: 25 July 2018
Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could use this to cause a system crash and a denial of service.
From the Ubuntu Security Team
Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly ensure that xattr information remained in inode bodies. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash).
Notes
| Author | Note |
|---|---|
| sbeattie | possible reproducer in bug report note that it depends on the ext4 inline_data feature, which is not the default. |
