CVSS: 5.5EPSS: 0%CPEs: 10EXPL: 0CVE-2024-27412 – power: supply: bq27xxx-i2c: Do not free non existing IRQ
https://notcve.org/view.php?id=CVE-2024-27412
In the Linux kernel, the following vulnerability has been resolved: power: supply: bq27xxx-i2c: Do not free non existing IRQ The bq27xxx i2c-client may not have an IRQ, in which case client->irq will be 0. bq27xxx_battery_i2c_probe() already has an if (client->irq) check wrapping the request_threaded_irq(). But bq27xxx_battery_i2c_remove() unconditionally calls free_irq(client->irq) leading to: [ 190.310742] ------------[ cut here ]------------ [ 190.310843] Trying to free already-free IRQ 0 [ 190.310861] WARNING: CPU: 2 PID: 1304 at kernel/irq/manage.c:1893 free_irq+0x1b8/0x310 Followed by a backtrace when unbinding the driver. Add an if (client->irq) to bq27xxx_battery_i2c_remove() mirroring probe() to fix this. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: alimentación: suministro: bq27xxx-i2c: no liberar IRQ no existente Es posible que el cliente bq27xxx i2c no tenga una IRQ, en cuyo caso client->irq será 0. bq27xxx_battery_i2c_probe( ) ya tiene una verificación if (cliente->irq) que envuelve request_threaded_irq(). Pero bq27xxx_battery_i2c_remove() llama incondicionalmente a free_irq(cliente->irq) lo que lleva a: [190.310742] ------------[ cortar aquí ]------------ [ 190.310843] Intentando liberar IRQ 0 [190.310861] que ya está libre ADVERTENCIA: CPU: 2 PID: 1304 en kernel/irq/manage.c:1893 free_irq+0x1b8/0x310 Seguido de un seguimiento al desvincular el controlador. Agregue un if (cliente->irq) a bq27xxx_battery_i2c_remove() mirroring probe() para solucionar este problema. • https://git.kernel.org/stable/c/76d2ed844def0cb8704d766924b07b2a918b3e30 https://git.kernel.org/stable/c/dafe9136be7b7fc30f1f3ca410c15b7cc65bee44 https://git.kernel.org/stable/c/1da9a4b55a6688e3a30c16d0cf2e7c6a90a684fb https://git.kernel.org/stable/c/e01820a94aea99296e500f54b3f36a2985061045 https://git.kernel.org/stable/c/e65fee45687fa2109e03056a696dc7d68a151296 https://git.kernel.org/stable/c/444ff00734f3878cd54ddd1ed5e2e6dbea9326d5 https://git.kernel.org/stable/c/ca4a2ddd2e69ca82ca5992d4c49649b2cbac3b74 https://git.kernel.org/stable/c/28960625adaaf3fa3d83c8d3596661d25 •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-27410 – wifi: nl80211: reject iftype change with mesh ID change
https://notcve.org/view.php?id=CVE-2024-27410
In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: reject iftype change with mesh ID change It's currently possible to change the mesh ID when the interface isn't yet in mesh mode, at the same time as changing it into mesh mode. This leads to an overwrite of data in the wdev->u union for the interface type it currently has, causing cfg80211_change_iface() to do wrong things when switching. We could probably allow setting an interface to mesh while setting the mesh ID at the same time by doing a different order of operations here, but realistically there's no userspace that's going to do this, so just disallow changes in iftype when setting mesh ID. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: wifi: nl80211: rechazar cambio de tipo con cambio de ID de malla Actualmente es posible cambiar el ID de malla cuando la interfaz aún no está en modo malla, al mismo tiempo que se cambia a modo malla. Esto lleva a una sobrescritura de datos en la unión wdev->u para el tipo de interfaz que tiene actualmente, causando que cfg80211_change_iface() haga cosas incorrectas al cambiar. Probablemente podríamos permitir configurar una interfaz para malla mientras configuramos la ID de malla al mismo tiempo haciendo un orden diferente de operaciones aquí, pero en realidad no hay ningún espacio de usuario que vaya a hacer esto, así que simplemente no permita cambios en iftype al configurar la ID de malla. • https://git.kernel.org/stable/c/7b0a0e3c3a88260b6fcb017e49f198463aa62ed1 https://git.kernel.org/stable/c/d38d31bbbb9dc0d4d71a45431eafba03d0bc150d https://git.kernel.org/stable/c/0cfbb26ee5e7b3d6483a73883f9f6157bca22ec9 https://git.kernel.org/stable/c/99eb2159680af8786104dac80528acd5acd45980 https://git.kernel.org/stable/c/063715c33b4c37587aeca2c83cf08ead0c542995 https://git.kernel.org/stable/c/930e826962d9f01dcd2220176134427358d112f2 https://git.kernel.org/stable/c/177d574be4b58f832354ab1ef5a297aa0c9aa2df https://git.kernel.org/stable/c/a2add961a5ed25cfd6a74f9ffb9e7ab6d •

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: HDMA: Add sync read before starting the DMA transfer in remote setup The Linked list element and pointer are not stored in the same memory as the HDMA controller register. If the doorbell register is toggled before the full write of the linked list a race condition error will occur. In remote setup we can only use a readl to the memory to assure the full write has occurred. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: dw-edma: HDMA: Añadida lectura sincronizada antes de iniciar la transferencia DMA en la configuración remota. El elemento de la lista vinculada y el puntero no se almacenan en la misma memoria que el registro del controlador HDMA. Si el registro del timbre se activa antes de la escritura completa de la lista vinculada, se producirá un error de condición de ejecución. • https://git.kernel.org/stable/c/e74c39573d35e9ac441090ff8183aa3dc2540649 https://git.kernel.org/stable/c/227ef58a9b0c372efba422e8886a8015a1509eba https://git.kernel.org/stable/c/17be6f5cb223f22e4733ed8fe8b2247cbb677716 https://git.kernel.org/stable/c/712a92a48158e02155b4b6b21e03a817f78c9b7e •
