Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Upgrade torvalds/linux to version 6.12.86, 6.18.27, 7.0.4 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Overflow in the cc1352_bootloader_rx function. An attacker can achieve arbitrary code execution, kernel memory disclosure, or denial of service by sending specially crafted serial data to the bootloader during firmware flashing mode, causing a heap out-of-bounds write in the receive buffer. This is only exploitable if the system is in firmware flashing mode and the attacker has control over the CC1352 co-processor's bootloader responses.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
