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.
