Summary
In the Linux kernel, the following vulnerability has been resolved: net: airoha: fix foe_check_time allocation size foe_check_time is declared as u16 pointer but was allocated with only ppe_num_entries bytes instead of ppe_num_entries * sizeof(u16). When airoha_ppe_foe_verify_entry() is called with hash >= ppe_num_entries/2, it writes beyond the allocated buffer, causing heap buffer overflow and potential kernel crash.
