Name of the Vulnerable Software and Affected Versions
Linux kernel version 5.10.30-rt37-tsn1-rt-ipipe
Description
The vulnerability is a use-after-free error that occurs during the reset of the igc driver. This error can cause the driver to attempt to free a socket buffer (skb) that has already been freed, leading to invalid memory accesses. The issue arises when the
igc poll() function runs while the controller is being reset, and the next to watch descriptor is not properly cleaned.Recommendations
To resolve this issue, update the Linux kernel to a version that includes the fix for this vulnerability. Specifically, ensure that the
igc driver is updated to properly clean the next to watch descriptor during the reset process.At the moment, there is no information about a newer version that contains a fix for this vulnerability.
