Description

staging: rtl8723bs: fix out-of-bounds read in OnBeacon ESR IE parsing

In the Linux kernel, the following vulnerability has been resolved:

staging: rtl8723bs: fix out-of-bounds read in OnBeacon ESR IE parsing

The Extended Supported Rates (ESR) IE handling in OnBeacon accessed

*(p + 1 + ielen) and *(p + 2 + ielen) without verifying that these

offsets lie within the received frame buffer. A malformed beacon with

an ESR IE positioned at the end of the buffer could cause an

out-of-bounds read, potentially triggering a kernel panic.

Add a boundary check to ensure that the ESR IE body and the subsequent

bytes are within the limits of the frame before attempting to access

them.

This prevents OOB reads caused by malformed beacon frames.

How this vulnerability can be exploited

This issue can be reached from an adjacent network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability high.
