| Vector | AV:L/AC:L/Au:S/C:C/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the net/hsr subsystem, specifically within the
prp get untagged frame() function. This function calls pskb copy() to allocate memory for frame->skb std, but lacks a check to verify if the allocation was successful. If pskb copy() fails and returns NULL, the code proceeds to call skb clone() with a NULL pointer, leading to a general protection fault and a system crash. This issue can occur during the handling of HSR (High-availability Seamless Redundancy) frames.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
