Published Aug 28, 2026
·
Updated

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