https://notcve.org/view.php?id=CVE-2024-38608
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix netif state handling mlx5e_suspend cleans resources only if netif_device_present() returns true. However, mlx5e_resume changes the state of netif, via mlx5e_nic_enable, only if reg_state == NETREG_REGISTERED. In the below case, the above leads to NULL-ptr Oops[1] and memory leaks: mlx5e_probe _mlx5e_resume mlx5e_attach_netdev mlx5e_nic_enable <-- netdev not reg, not calling netif_device_attach() register_netdev <-- failed for some reason. ERROR_FLOW: _mlx5e_suspend <-- netif_device_present return false, resources aren't freed :( Hence, clean resources in this case as well.

In the Linux kernel, the following vulnerability has been resolved: macintosh/via-macii: Fix "BUG: sleeping function called from invalid context" The via-macii ADB driver calls request_irq() after disabling hard interrupts. But disabling interrupts isn't necessary here because the VIA shift register interrupt was masked during VIA1 initialization. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: macintosh/via-macii: Corrección "ERROR: función de suspensión llamada desde un contexto no válido" El controlador ADB via-macii llama a request_irq() después de deshabilitar las interrupciones bruscas. Pero aquí no es necesario deshabilitar las interrupciones porque la interrupción del registro de desplazamiento de VIA se enmascaró durante la inicialización de VIA1. • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/e4ff8bcfb2841fe4e17e5901578b632adb89036d https://git.kernel.org/stable/c/1e9c3f2caec548cfa7a65416ec4e6006e542f18e https://git.kernel.org/stable/c/280619bbdeac186fb320fab3d61122d2a085def8 https://git.kernel.org/stable/c/010d4cb19bb13f423e3e746b824f314a9bf3e9a9 https://git.kernel.org/stable/c/787fb79efc15b3b86442ecf079b8148f173376d7 https://git.kernel.org/stable/c/d43a8c7ec0841e0ff91a968770aeca83f0fd4c56 https://git.kernel.org/stable/c/5900a88e897e6deb1bdce09ee34167a81 •
CVSS: 8.8EPSS: 0%CPEs: 7EXPL: 0CVE-2024-38605 – ALSA: core: Fix NULL module pointer assignment at card init
https://notcve.org/view.php?id=CVE-2024-38605
In the Linux kernel, the following vulnerability has been resolved: ALSA: core: Fix NULL module pointer assignment at card init The commit 81033c6b584b ("ALSA: core: Warn on empty module") introduced a WARN_ON() for a NULL module pointer passed at snd_card object creation, and it also wraps the code around it with '#ifdef MODULE'. This works in most cases, but the devils are always in details. "MODULE" is defined when the target code (i.e. the sound core) is built as a module; but this doesn't mean that the caller is also built-in or not. Namely, when only the sound core is built-in (CONFIG_SND=y) while the driver is a module (CONFIG_SND_USB_AUDIO=m), the passed module pointer is ignored even if it's non-NULL, and card->module remains as NULL. This would result in the missing module reference up/down at the device open/close, leading to a race with the code execution after the module removal. For addressing the bug, move the assignment of card->module again out of ifdef. • https://git.kernel.org/stable/c/81033c6b584b44514cbb16fffc26ca29a0fa6270 https://git.kernel.org/stable/c/d7ff29a429b56f04783152ad7bbd7233b740e434 https://git.kernel.org/stable/c/e7e0ca200772bdb2fdc6d43d32d341e87a36f811 https://git.kernel.org/stable/c/e007476725730c1a68387b54b7629486d8a8301e https://git.kernel.org/stable/c/e644036a3e2b2c9b3eee3c61b5d31c2ca8b5ba92 https://git.kernel.org/stable/c/c935e72139e6d523defd60fe875c01eb1f9ea5c5 https://git.kernel.org/stable/c/6b8374ee2cabcf034faa34e69a855dc496a9ec12 https://git.kernel.org/stable/c/39381fe7394e5eafac76e7e9367e73511 • CWE-476: NULL Pointer Dereference •

In the Linux kernel, the following vulnerability has been resolved: block: refine the EOF check in blkdev_iomap_begin blkdev_iomap_begin rounds down the offset to the logical block size before stashing it in iomap->offset and checking that it still is inside the inode size. Check the i_size check to the raw pos value so that we don't try a zero size write if iter->pos is unaligned. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bloque: refina la comprobación de EOF en blkdev_iomap_begin blkdev_iomap_begin redondea hacia abajo el desplazamiento al tamaño del bloque lógico antes de guardarlo en iomap->offset y comprobar que todavía está dentro del tamaño del inodo.

In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action() fails, the irq vector is not freed, which leads to a memory leak.
