Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the btrfs component of the Linux kernel and involves an error in handling chunk tree lookup in the
btrfs relocate sys chunks() function. This error can lead to corruption and potentially allow an attacker to cause a denial of service. The vulnerability is caused by two impossible conditions: the search key being set up to look for a chunk tree item with an offset of -1, and the found key corresponding to a chunk item after a successful search. The offset is decremented by 1 before the next loop, making it impossible to find a chunk item due to alignment and size constraints.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
