An integer coercion error was found in the openvswitch kernel module. Given
a sufficiently large number of actions, while copying and reserving memory
for a new action of a new flow, the reserve_sfa_size() function does not
return -EMSGSIZE as expected, potentially leading to an out-of-bounds write
access. This flaw allows a local user to crash or potentially escalate
their privileges on the system.
