1 security issue in forky high

There is 1 open security issue in forky.

1 important issue:
  • CVE-2025-11568: A data corruption vulnerability has been identified in the luksmeta utility when used with the LUKS1 disk encryption format. An attacker with the necessary permissions can exploit this flaw by writing a large amount of metadata to an encrypted device. The utility fails to correctly validate the available space, causing the metadata to overwrite and corrupt the user's encrypted data. This action leads to a permanent loss of the stored information. Devices using the LUKS formats other than LUKS1 are not affected by this issue.

The utility fails to correctly validate the available space, causing the metadata to overwrite and corrupt the user's encrypted data. This action leads to a permanent loss of the stored information.

testing migrations
  • excuses:
    • Migration status for luksmeta (9-4 to 10-1): Waiting for test results or another package, or too young (no action required now - check later)
    • Issues preventing migration:
    • ∙ ∙ Too young, only 1 of 2 days old
    • Additional info (not blocking):
    • ∙ ∙ Piuparts tested OK - https://piuparts.debian.org/sid/source/l/luksmeta.html
    • ∙ ∙ Reproducible on amd64 - info ♻
    • ∙ ∙ Reproducible on arm64 - info ♻
    • Not considered
