CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-26655 – Fix memory leak in posix_clock_open()
https://notcve.org/view.php?id=CVE-2024-26655
In the Linux kernel, the following vulnerability has been resolved: Fix memory leak in posix_clock_open() If the clk ops.open() function returns an error, we don't release the pccontext we allocated for this clock. Re-organize the code slightly to make it all more obvious. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Reparar la pérdida de memoria en posix_clock_open() Si la función clk ops.open() devuelve un error, no liberamos el contexto de pc que asignamos para este reloj. Reorganice ligeramente el código para que sea más obvio. • https://git.kernel.org/stable/c/60c6946675fc06dd2fd2b7a4b6fd1c1f046f1056 https://git.kernel.org/stable/c/a88649b49523e8cbe95254440d803e38c19d2341 https://git.kernel.org/stable/c/0200dd7ed2335469955d7e69cc1a6fa7df1f3847 https://git.kernel.org/stable/c/5b4cdd9c5676559b8a7c944ac5269b914b8c0bb8 •
CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-26654 – ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs
https://notcve.org/view.php?id=CVE-2024-26654
In the Linux kernel, the following vulnerability has been resolved: ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs The dreamcastcard->timer could schedule the spu_dma_work and the spu_dma_work could also arm the dreamcastcard->timer. When the snd_pcm_substream is closing, the aica_channel will be deallocated. But it could still be dereferenced in the worker thread. The reason is that del_timer() will return directly regardless of whether the timer handler is running or not and the worker could be rescheduled in the timer handler. As a result, the UAF bug will happen. The racy situation is shown below: (Thread 1) | (Thread 2) snd_aicapcm_pcm_close() | • https://git.kernel.org/stable/c/198de43d758ca2700e2b52b49c0b189b4931466c https://git.kernel.org/stable/c/eeb2a2ca0b8de7e1c66afaf719529154e7dc60b2 https://git.kernel.org/stable/c/4206ad65a0ee76920041a755bd3c17c6ba59bba2 https://git.kernel.org/stable/c/aa39e6878f61f50892ee2dd9d2176f72020be845 https://git.kernel.org/stable/c/8c990221681688da34295d6d76cc2f5b963e83f5 https://git.kernel.org/stable/c/9d66ae0e7bb78b54e1e0525456c6b54e1d132046 https://git.kernel.org/stable/c/61d4787692c1fccdc268ffa7a891f9c149f50901 https://git.kernel.org/stable/c/e955e8a7f38a856fc6534ba4e6bffd4d5 •
CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-26653 – usb: misc: ljca: Fix double free in error handling path
https://notcve.org/view.php?id=CVE-2024-26653
In the Linux kernel, the following vulnerability has been resolved: usb: misc: ljca: Fix double free in error handling path When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), callback function ljca_auxdev_release calls kfree(auxdev->dev.platform_data) to free the parameter data of the function ljca_new_client_device. The callers of ljca_new_client_device shouldn't call kfree() again in the error handling path to free the platform data. Fix this by cleaning up the redundant kfree() in all callers and adding kfree() the passed in platform_data on errors which happen before auxiliary_device_init() succeeds . En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: misc: ljca: corrige el doble libre en la ruta de manejo de errores Cuando auxiliar_device_add() devuelve un error y luego llama a auxiliar_device_uninit(), la función de devolución de llamada ljca_auxdev_release llama a kfree(auxdev->dev.platform_data ) para liberar los datos de los parámetros de la función ljca_new_client_device. Las personas que llaman a ljca_new_client_device no deberían volver a llamar a kfree() en la ruta de manejo de errores para liberar los datos de la plataforma. Solucione este problema limpiando el kfree() redundante en todas las personas que llaman y agregando kfree() los datos de plataforma pasados en los errores que ocurren antes de queauxiliar_device_init() tenga éxito. • https://git.kernel.org/stable/c/acd6199f195d6de814ac4090ce0864a613b1580e https://git.kernel.org/stable/c/420babea4f1881a7c4ea22a8e218b8c6895d3f21 https://git.kernel.org/stable/c/8a9f653cc852677003c23ee8075e3ed8fb4743c9 https://git.kernel.org/stable/c/7c9631969287a5366bc8e39cd5abff154b35fb80 •

In the Linux kernel, the following vulnerability has been resolved: net: pds_core: Fix possible double free in error handling path When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release calls kfree(padev) to free memory.
