CVE-2024-26697

Severity CVSS v4.0:
Pending analysis
Type:
CWE-787 Out-of-bounds Write
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nilfs2: fix data corruption in dsync block recovery for small block sizes<br /> <br /> The helper function nilfs_recovery_copy_block() of<br /> nilfs_recovery_dsync_blocks(), which recovers data from logs created by<br /> data sync writes during a mount after an unclean shutdown, incorrectly<br /> calculates the on-page offset when copying repair data to the file&amp;#39;s page<br /> cache. In environments where the block size is smaller than the page<br /> size, this flaw can cause data corruption and leak uninitialized memory<br /> bytes during the recovery process.<br /> <br /> Fix these issues by correcting this byte offset calculation on the page.
