"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: appletb-kbd: fix \"appletb_backlight\" backlight device reference counting\n\nDuring appletb_kbd_probe, probe attempts to get the backlight device\nby name. When this happens backlight_device_get_by_name looks for a\ndevice in the backlight class which has name \"appletb_backlight\" and\nupon finding a match it increments the reference count for the device\nand returns it to the caller. However this reference is never released\nleading to a reference leak.\n\nFix this by decrementing the backlight device reference count on removal\nvia put_device and on probe failure."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: HID: appletb-kbd: correcci\u00f3n del conteo de referencias del dispositivo de retroiluminaci\u00f3n \"appletb_backlight\". Durante appletb_kbd_probe, la sonda intenta obtener el dispositivo de retroiluminaci\u00f3n por nombre. Cuando esto ocurre, backlight_device_get_by_name busca un dispositivo en la clase de retroiluminaci\u00f3n con el nombre \"appletb_backlight\" y, al encontrar una coincidencia, incrementa el conteo de referencias del dispositivo y lo devuelve al invocador. Sin embargo, esta referencia nunca se libera, lo que provoca una fuga de referencias. Para solucionar esto, disminuya el conteo de referencias del dispositivo de retroiluminaci\u00f3n al eliminarlo mediante put_device y si la sonda falla."

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
