CVE-2022-2639

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...

CVE-2022-2639

CVE-2022-2639 affects the Linux kernel openvswitch module. The root cause is an integer coercion error in reserve_sfa_size() that can fail to return -EMSGSIZE under heavy action counts, risking an out-of-bounds write and local privilege escalation or denial of service. Public details in connected...
