https://notcve.org/view.php?id=CVE-2024-38612
In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix invalid unregister error path The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL is not defined. In that case if seg6_hmac_init() fails, the genl_unregister_family() isn't called. This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible use-after-free and null-ptr-deref") replaced unregister_pernet_subsys() with genl_unregister_family() in this error path. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ipv6: sr: corrige la ruta de error de cancelación de registro no válida La ruta de error de seg6_init() es incorrecta en caso de que CONFIG_IPV6_SEG6_LWTUNNEL no esté definido. En ese caso, si seg6_hmac_init() falla, no se llama a genl_unregister_family(). Este problema existe desde que el commit 46738b1317e1 ("ipv6: sr: agregar opción para controlar la compatibilidad con lwtunnel") y el commit 5559cea2d5aa ("ipv6: sr: corregir posible use-after-free y null-ptr-deref") reemplazó unregister_pernet_subsys() con genl_unregister_family() en esta ruta de error. • https://git.kernel.org/stable/c/46738b1317e169b281ad74690276916e24d1be6d https://git.kernel.org/stable/c/10610575a3ac2a702bf5c57aa931beaf847949c7 https://git.kernel.org/stable/c/646cd236c55e2cb5f146fc41bbe4034c4af5b2a4 https://git.kernel.org/stable/c/00e6335329f23ac6cf3105931691674e28bc598c https://git.kernel.org/stable/c/1a63730fb315bb1bab97edd69ff58ad45e04bb01 https://git.kernel.org/stable/c/e77a3ec7ada84543e75722a1283785a6544de925 https://git.kernel.org/stable/c/3398a40dccb88d3a7eef378247a023a78472db66 https://git.kernel.org/stable/c/85a70ff1e572160f1eeb096ed48d09a1c • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2024-38611
In the Linux kernel, the following vulnerability has been resolved: media: i2c: et8ek8: Don't strip remove function when driver is builtin Using __exit for the remove function results in the remove callback being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets unbound (e.g. using sysfs or hotplug), the driver is just removed without the cleanup being performed. This results in resource leaks. Fix it by compiling in the remove callback unconditionally. This also fixes a W=1 modpost warning: WARNING: modpost: drivers/media/i2c/et8ek8/et8ek8: section mismatch in reference: et8ek8_i2c_driver+0x10 (section: .data) -> et8ek8_remove (section: .exit.text) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: medios: i2c: et8ek8: No eliminar la función de eliminación cuando el controlador está integrado.

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.

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.

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 •
