Description
In the Linux kernel, the following vulnerability has been resolved: batman-adv: fix integer overflow on buff_pos Fixing an integer overflow present in batadv_iv_ogm_send_to_if. The size check is done using the int type in batadv_iv_ogm_aggr_packet whereas the buff_pos variable uses the s16 type. This could lead to an out-of-bound read.

Can you explain this vulnerability to me?

This vulnerability is an integer overflow in the Linux kernel component batman-adv, specifically in the function batadv_iv_ogm_send_to_if. The issue arises because a size check uses an int type, while the buff_pos variable uses a signed 16-bit integer (s16) type. This mismatch can cause an integer overflow, potentially leading to an out-of-bound read.


How can this vulnerability impact me? :

The integer overflow can cause an out-of-bound read in the Linux kernel's batman-adv module. This may lead to unexpected behavior such as crashes, data corruption, or potential security risks like information disclosure or privilege escalation, depending on how the out-of-bound read is exploited.
