| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a logic leak in ring data allocation and free operations in the Linux kernel's Atlantic driver. When the system is under stress and encounters a memory allocation error, the
aq ring free function could be called multiple times on the same ring, leading to a double free error. The ring pointer was incorrectly used as an indicator of failure, as only ring data is allocated and deallocated, while the ring itself is an array member. To resolve this, the ring allocation functions have been modified to return error codes directly, simplifying error handling and eliminating the aq ring free function on higher layers.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
