https://notcve.org/view.php?id=CVE-2024-39495
In the Linux kernel, the following vulnerability has been resolved: greybus: Fix use-after-free bug in gb_interface_release due to race condition. In gb_interface_create, &intf->mode_switch_completion is bound with gb_interface_mode_switch_work. Then it will be started by gb_interface_request_mode_switch. Here is the relevant code. if (!queue_work(system_long_wq, &intf->mode_switch_work)) { ... } If we call gb_interface_release to make cleanup, there may be an unfinished work. This function will call kfree to free the object "intf". • https://git.kernel.org/stable/c/74cd0a421896b2e07eafe7da4275302bfecef201 https://git.kernel.org/stable/c/2b6bb0b4abfd79b8698ee161bb73c0936a2aaf83 https://git.kernel.org/stable/c/fb071f5c75d4b1c177824de74ee75f9dd34123b9 https://git.kernel.org/stable/c/9a733d69a4a59c2d08620e6589d823c24be773dc https://git.kernel.org/stable/c/0b8fba38bdfb848fac52e71270b2aa3538c996ea https://git.kernel.org/stable/c/03ea2b129344152157418929f06726989efc0445 https://git.kernel.org/stable/c/5c9c5d7f26acc2c669c1dcf57d1bb43ee99220ce • CWE-416: Use After Free •

In the Linux kernel, the following vulnerability has been resolved: ima: Fix use-after-free on a dentry's dname.name ->d_name.name can change on rename and the earlier value can be freed; there are conditions sufficient to stabilize it (->d_lock on dentry, ->d_lock on its parent, ->i_rwsem exclusive on the parent's inode, rename_lock), but none of those are met at any of the sites. Take a stable snapshot of the name instead. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ima: corrige el use-after-free en dentry dname.name ->d_name.name puede cambiar al cambiar el nombre y el valor anterior se puede liberar; existen condiciones suficientes para estabilizarlo (->d_lock on dentry, ->d_lock on its parent, ->i_rwsem exclusivo en el inodo del padre, rename_lock), pero ninguna de ellas se cumple en ninguno de los sitios.

CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2024-39484 – mmc: davinci: Don't strip remove function when driver is builtin
https://notcve.org/view.php?id=CVE-2024-39484
In the Linux kernel, the following vulnerability has been resolved: mmc: davinci: Don't strip remove function when driver is builtin Using __exit for the remove function results in the remove callback being discarded with CONFIG_MMC_DAVINCI=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/mmc/host/davinci_mmc: section mismatch in reference: davinci_mmcsd_driver+0x10 (section: .data) -> davinci_mmcsd_remove (section: .exit.text) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mmc: davinci: no eliminar la función de eliminación cuando el controlador está integrado. El uso de __exit para la función de eliminación hace que la devolución de llamada de eliminación se descarte con CONFIG_MMC_DAVINCI=y. • https://git.kernel.org/stable/c/b4cff4549b7a8c5fc8b88e3493b6287555f0512c https://git.kernel.org/stable/c/6ff7cfa02baabec907f6f29ea76634e6256d2ec4 https://git.kernel.org/stable/c/aea35157bb9b825faa0432bd0f7fbea37ff39aa1 https://git.kernel.org/stable/c/5ee241f72edc6dce5051a5f100eab6cc019d873e https://git.kernel.org/stable/c/7590da4c04dd4aa9c262da0231e978263861c6eb https://git.kernel.org/stable/c/1d5ed0efe51d36b9ae9b64f133bf41cdbf56f584 https://git.kernel.org/stable/c/55c421b364482b61c4c45313a535e61ed5ae4ea3 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2024-39482 – bcache: fix variable length array abuse in btree_iter
https://notcve.org/view.php?id=CVE-2024-39482
In the Linux kernel, the following vulnerability has been resolved: bcache: fix variable length array abuse in btree_iter btree_iter is used in two ways: either allocated on the stack with a fixed size MAX_BSETS, or from a mempool with a dynamic size based on the specific cache set. Previously, the struct had a fixed-length array of size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized iterators, which causes UBSAN to complain. This patch uses the same approach as in bcachefs's sort_iter and splits the iterator into a btree_iter with a flexible array member and a btree_iter_stack which embeds a btree_iter as well as a fixed-length data array. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bcache: corrige el abuso de matriz de longitud variable en btree_iter btree_iter se usa de dos maneras: ya sea asignado en la pila con un tamaño fijo MAX_BSETS, o desde un mempool con un tamaño dinámico basado en el conjunto de caché específico. Anteriormente, la estructura tenía una matriz de longitud fija de tamaño MAX_BSETS que estaba indexada fuera de los límites para los iteradores de tamaño dinámico, lo que provoca que UBSAN se queje. Este parche utiliza el mismo enfoque que en sort_iter de bcachefs y divide el iterador en un btree_iter con un miembro de matriz flexible y un btree_iter_stack que incorpora un btree_iter así como una matriz de datos de longitud fija. • https://git.kernel.org/stable/c/2c3d7b03b658dc8bfa6112b194b67b92a87e081b https://git.kernel.org/stable/c/5a1922adc5798b7ec894cd3f197afb6f9591b023 https://git.kernel.org/stable/c/934e1e4331859183a861f396d7dfaf33cb5afb02 https://git.kernel.org/stable/c/6479b9f41583b013041943c4602e1ad61cec8148 https://git.kernel.org/stable/c/0c31344e22dd8d6b1394c6e4c41d639015bdc671 https://git.kernel.org/stable/c/3a861560ccb35f2a4f0a4b8207fa7c2a35fc7f31 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39480 – kdb: Fix buffer overflow during tab-complete
https://notcve.org/view.php?id=CVE-2024-39480
In the Linux kernel, the following vulnerability has been resolved: kdb: Fix buffer overflow during tab-complete Currently, when the user attempts symbol completion with the Tab key, kdb will use strncpy() to insert the completed symbol into the command buffer. Unfortunately it passes the size of the source buffer rather than the destination to strncpy() with predictably horrible results. Most obviously if the command buffer is already full but cp, the cursor position, is in the middle of the buffer, then we will write past the end of the supplied buffer. Fix this by replacing the dubious strncpy() calls with memmove()/memcpy() calls plus explicit boundary checks to make sure we have enough space before we start moving characters around. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: kdb: corrige el desbordamiento del búfer durante la finalización de tabulación Actualmente, cuando el usuario intenta completar el símbolo con la tecla Tab, kdb usará strncpy() para insertar el símbolo completado en el búfer de comando. Desafortunadamente, pasa el tamaño del búfer de origen en lugar del destino a strncpy() con resultados predeciblemente horribles. Lo más obvio es que si el búfer de comando ya está lleno pero cp, la posición del cursor, está en el medio del búfer, entonces escribiremos más allá del final del búfer proporcionado. • https://git.kernel.org/stable/c/fb824a99e148ff272a53d71d84122728b5f00992 https://git.kernel.org/stable/c/ddd2972d8e2dee3b33e8121669d55def59f0be8a https://git.kernel.org/stable/c/cfdc2fa4db57503bc6d3817240547c8ddc55fa96 https://git.kernel.org/stable/c/f636a40834d22e5e3fc748f060211879c056cd33 https://git.kernel.org/stable/c/33d9c814652b971461d1e30bead6792851c209e7 https://git.kernel.org/stable/c/107e825cc448b7834b31e8b1b3cf0f57426d46d5 https://git.kernel.org/stable/c/f694da720dcf795dc3eb97bf76d220213f76aaa7 https://git.kernel.org/stable/c/e9730744bf3af04cda23799029342aa3c • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-121: Stack-based Buffer Overflow •
