| Vector | AV: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 issue is related to the llc conn handler() function in the Linux kernel's LLC (Logical Link Control) module. The function initialises local variables {saddr,daddr}.mac based on skb in llc pdu decode sa()/llc pdu decode da() and passes them to llc lookup(). However, the initialisation is done only when skb->protocol is htons(ETH P 802 2), otherwise, llc lookup established() and llc lookup listener() will read garbage. The missing initialisation existed prior to commit 211ed865108e ("net: delete all instances of special processing for token ring").
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
