Details

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: pcie: Fix integer overflow in iwlwritetouserbuf An integer overflow occurs in the iwlwritetouserbuf() function, which is called by the iwldbgfsmonitordataread() function. static bool iwlwritetouserbuf(char _user *userbuf, ssizet count, void *buf, ssizet size, ssize_t *bytes_copied) { int buf_size_left = count - *bytes_copied; buf_size_left = buf_size_left - (buf_size_left % sizeof(u32)); if (size > bufsizeleft) size = buf_size_left; If the user passes a SIZE_MAX value to the "ssize_t count" parameter, the ssize_t count parameter is assigned to "int buf_size_left". Then compare "size" with "bufsizeleft" . Here, "bufsizeleft" is a negative number, so "*size" is assigned "bufsizeleft" and goes into the third argument of the copytouser function, causing a heap overflow. This is not a security vulnerability because iwldbgfsmonitordataread() is a debugfs operation with 0400 privileges.
