GHSA-W6WH-QR7X-H932

Vulnerability from github – Published: 2022-09-02 00:01 – Updated: 2022-09-08 00:00

Details

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.

Severity ?

7.8 (High)
