CVE-2022-2639 (GCVE-0-2022-2639)

Vulnerability from cvelistv5 – Published: 2022-09-01 20:32 – Updated: 2024-08-03 00:46
VLAI
Summary
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.
