certfr-2026-avi-1375

fkie_cve-2026-98761

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

usb: typec: tcpm: recover after failure to start the frs ams

Reset the port if the tcpm fails to start the FAST_ROLE_SWAP AMS by initiating error recovery on it.

This helps in cases where some cables (incorrectly) signal an FRS to an FRS capable port during disconnection. The TCPC autonomously starts sourcing VBUS on detecting the FRS signal. However, the VBUS sourcing is left on when the FAST_ROLE_SWAP AMS fails to start (as tcpm_sink_tx_ok is 0 as CC is open due to the cable disconnect). This is because the code sets the state to INVALID_STATE without resetting the port state.

WID-SEC-W-2026-4019 — Linux Kernel: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen nicht näher spezifizierten Angriff durchzuführen, möglicherweise einen Denial-of-Service-Angriff auszulösen, Daten zu manipulieren oder offenzulegen oder Sicherheitsmaßnahmen zu umgehen.
