In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: fix aq_vec index out of range error
The final update statement of the for loop exceeds the array range, the
dereference of self->aq_vec[i] is not checked and then leads to the
index out of range error.
Also fixed this kind of coding style in other for loop.

v2. fixed "warning: variable 'aq_vec' set but not used"
v3. simplified a for loop
A vulnerability was found in the Linux kernel's Aquantia Atlantic driver, where a lack of proper bounds checking during loop indexing can lead to an out-of-bounds access. This can lead to undefined system behavior and a denial of service.
Отчет
This vulnerability in the Aquantia network driver (atlantic) allows out-of-bounds access to the aq_vec[] array, which can lead to a kernel crash. However, triggering this issue requires privileges, as it occurs in internal kernel functions like aq_nic_stop() and aq_vec_isr(), typically invoked during device suspend or shutdown. This bug was observable through a UBSAN report in aq_nic_stop().
Меры по смягчению последствий
To mitigate this issue, prevent module atlantic from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
