Detailsinfo

A vulnerability was found in Linux Kernel up to 6.12.61/6.17.11/6.18.0. It has been classified as problematic. This affects an unknown code of the component ESR IE Parser. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality. The summary by CVE is:

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.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2025-68254 since 12/16/2025. The technical details are unknown and an exploit is not publicly available.
