CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2020-36788 – drm/nouveau: avoid a use-after-free when BO init fails
https://notcve.org/view.php?id=CVE-2020-36788
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: avoid a use-after-free when BO init fails nouveau_bo_init() is backed by ttm_bo_init() and ferries its return code back to the caller. On failures, ttm_bo_init() invokes the provided destructor which should de-initialize and free the memory. Thus, when nouveau_bo_init() returns an error the gem object has already been released and the memory freed by nouveau_bo_del_ttm(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/nouveau: evita un use after free cuando falla BO init nouveau_bo_init() está respaldado por ttm_bo_init() y envía su código de retorno de regreso a la persona que llama. En caso de falla, ttm_bo_init() invoca el destructor proporcionado que debería desinicializar y liberar la memoria. Por lo tanto, cuando nouveau_bo_init() devuelve un error, el objeto gema ya ha sido liberado y la memoria ha sido liberada por nouveau_bo_del_ttm(). • https://git.kernel.org/stable/c/019cbd4a4feb3aa3a917d78e7110e3011bbff6d5 https://git.kernel.org/stable/c/f86e19d918a85492ad1a01fcdc0ad5ecbdac6f96 https://git.kernel.org/stable/c/548f2ff8ea5e0ce767ae3418d1ec5308990be87d https://git.kernel.org/stable/c/bcf34aa5082ee2343574bc3f4d1c126030913e54 •

https://notcve.org/view.php?id=CVE-2021-47358
In the Linux kernel, the following vulnerability has been resolved: staging: greybus: uart: fix tty use after free User space can hold a tty open indefinitely and tty drivers must not release the underlying structures until the last user is gone. Switch to using the tty-port reference counter to manage the life time of the greybus tty state to avoid use after free after a disconnect. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: staging: greybus: uart: corrige el use after free de tty. El espacio de usuario puede mantener un tty abierto indefinidamente y los controladores de tty no deben liberar las estructuras subyacentes hasta que el último usuario se haya ido. Cambie al uso del contador de referencia del puerto tty para administrar la vida útil del estado tty de greybus para evitar su uso después de una desconexión. • https://git.kernel.org/stable/c/a18e15175708d39abbe9746ddc3479466b7800c3 https://git.kernel.org/stable/c/92b67aaafb7c449db9f0c3dcabc0ff967cb3a42d https://git.kernel.org/stable/c/64062fcaca8872f063ec9da011e7bf30470be33f https://git.kernel.org/stable/c/a5cfd51f6348e8fd7531461366946039c29c7e69 https://git.kernel.org/stable/c/4dc56951a8d9d61d364d346c61a5f1d70b4f5e14 https://git.kernel.org/stable/c/b9e697e60ce9890e9258a73eb061288e7d68e5e6 https://git.kernel.org/stable/c/9872ff6fdce8b229f01993b611b5d1719cb70ff1 https://git.kernel.org/stable/c/92dc0b1f46e12cfabd28d709bb34f7a39 •

In the Linux kernel, the following vulnerability has been resolved: atm: iphase: fix possible use-after-free in ia_module_exit() This module's remove path calls del_timer(). However, that function does not wait until the timer handler finishes. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling del_timer_sync(), which makes sure the timer handler has finished, and unable to re-schedule itself.
