Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contains a flaw within the libiscsi component. Specifically, the iscsi conn->dd data field is initialized regardless of whether memory allocation succeeds. If ib fast reg mr allocation fails during iSER setup, this leads to a kernel panic due to an invalid pointer dereference during connection teardown. The issue occurs when memory is not allocated (dd size == 0).
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
