| Vetor | AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.2.3
Description
The issue is caused by an integer overflow and out-of-bounds read in the set geometry function in drivers/block/floppy.c. This can be triggered by an unprivileged local user when a floppy disk has been inserted. It may allow an attacker to cause a denial of service or disclose sensitive information.
Recommendations
For Linux kernel versions prior to 5.2.3, update to version 5.2.3 or later to resolve the issue. As a temporary workaround, consider disabling the floppy disk driver to minimize the risk of exploitation. Restrict access to the floppy device to prevent unprivileged users from inserting floppy disks.
Correção
Integer Overflow
Out of bounds Read
