Severity CVSS v4.0:
Pending analysis
Type:
CWE-362
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
xfrm: state: initialize state_ptrs earlier in xfrm_state_find<br />
<br />
In case of preemption, xfrm_state_look_at will find a different<br />
pcpu_id and look up states for that other CPU. If we matched a state<br />
for CPU2 in the state_cache while the lookup started on CPU1, we will<br />
jump to "found", but the "best" state that we got will be ignored and<br />
we will enter the "acquire" block. This block uses state_ptrs, which<br />
isn&#39;t initialized at this point.<br />
<br />
Let&#39;s initialize state_ptrs just after taking rcu_read_lock. This will<br />
also prevent a possible misuse in the future, if someone adjusts this<br />
function.
