Name of the Vulnerable Software and Affected Versions: openvswitch versions prior to v5.4.223 Linux Kernel versions prior to v5.4.223 Description: The issue is related to a switch from WARN to pr warn in openvswitch. The actual impact and attack plausibility have not yet been proven...

kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size()

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 reservesfasize function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write...
