CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 2.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows an attacker with physical access to disclose sensitive information.
The vulnerability exists due to an out-of-bounds read in p54_rx_eeprom_readback() when processing a device-supplied EEPROM readback frame. An attacker with physical access can send a truncated frame with a matching advertised length to disclose sensitive information.
The issue can be triggered by a malicious USB device.
