CVE-2023-34256

Published: 31 May 2023

** DISPUTED ** An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against attackers with the stated "When modifying the block device while it is mounted by the filesystem" access.

From the Ubuntu Security Team

It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle block device modification while it is mounted. A privileged attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information.

Notes

AuthorNote
Priority reason:
Requires privileged access to the block device that is mounted.
rodrigo-zaiden
disputed CVE as it is claimed that it is expected to have
the kernel crashed if a block device is modified while mounted.
