https://notcve.org/view.php?id=CVE-2024-35806
In the Linux kernel, the following vulnerability has been resolved: soc: fsl: qbman: Always disable interrupts when taking cgr_lock smp_call_function_single disables IRQs when executing the callback. To prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere. This is already done by qman_update_cgr and qman_delete_cgr; fix the other lockers. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: soc:fsl:qbman: Desactiva siempre las interrupciones al tomar cgr_lock smp_call_function_single desactiva las IRQ al ejecutar la devolución de llamada. Para evitar interbloqueos, debemos desactivar las IRQ cuando llevemos cgr_lock a otro lugar. Esto ya lo hacen qman_update_cgr y qman_delete_cgr; arreglar los otros casilleros. • https://git.kernel.org/stable/c/96f413f47677366e0ae03797409bfcc4151dbf9e https://git.kernel.org/stable/c/a85c525bbff4d7467d7f0ab6fed8e2f787b073d6 https://git.kernel.org/stable/c/29cd9c2d1f428c281962135ea046a9d7bda88d14 https://git.kernel.org/stable/c/5b10a404419f0532ef3ba990c12bebe118adb6d7 https://git.kernel.org/stable/c/b56a793f267679945d1fdb9a280013bd2d0ed7f9 https://git.kernel.org/stable/c/62c3ecd2833cff0eff4a82af4082c44ca8d2518a https://git.kernel.org/stable/c/dd199e5b759ffe349622a4b8fbcafc51fc51b1ec https://git.kernel.org/stable/c/e6378314bb920acb39013051fa65d8f9f •

In the Linux kernel, the following vulnerability has been resolved: dm snapshot: fix lockup in dm_exception_table_exit There was reported lockup when we exit a snapshot with many exceptions. Fix this by adding "cond_resched" to the loop that frees the exceptions. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dm snapshot: corregido el bloqueo en dm_exception_table_exit Se informó un bloqueo cuando salimos de un snapshot con muchas excepciones.

CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-35803 – x86/efistub: Call mixed mode boot services on the firmware's stack
https://notcve.org/view.php?id=CVE-2024-35803
In the Linux kernel, the following vulnerability has been resolved: x86/efistub: Call mixed mode boot services on the firmware's stack Normally, the EFI stub calls into the EFI boot services using the stack that was live when the stub was entered. According to the UEFI spec, this stack needs to be at least 128k in size - this might seem large but all asynchronous processing and event handling in EFI runs from the same stack and so quite a lot of space may be used in practice. In mixed mode, the situation is a bit different: the bootloader calls the 32-bit EFI stub entry point, which calls the decompressor's 32-bit entry point, where the boot stack is set up, using a fixed allocation of 16k. This stack is still in use when the EFI stub is started in 64-bit mode, and so all calls back into the EFI firmware will be using the decompressor's limited boot stack. Due to the placement of the boot stack right after the boot heap, any stack overruns have gone unnoticed. However, commit 5c4feadb0011983b ("x86/decompressor: Move global symbol references to C code") moved the definition of the boot heap into C code, and now the boot stack is placed right at the base of BSS, where any overruns will corrupt the end of the .data section. While it would be possible to work around this by increasing the size of the boot stack, doing so would affect all x86 systems, and mixed mode systems are a tiny (and shrinking) fraction of the x86 installed base. So instead, record the firmware stack pointer value when entering from the 32-bit firmware, and switch to this stack every time a EFI boot service call is made. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: x86/efistub: llame a los servicios de arranque en modo mixto en la pila del firmware. • https://git.kernel.org/stable/c/2149f8a56e2ed345c7a4d022a79f6b8fc53ae926 https://git.kernel.org/stable/c/930775060ca348b8665f60eef14b204172d14f31 https://git.kernel.org/stable/c/fba7ee7187581b5bc222003e73e2592b398bb06d https://git.kernel.org/stable/c/725351c036452b7db5771a7bed783564bc4b99cc https://git.kernel.org/stable/c/cefcd4fe2e3aaf792c14c9e56dab89e3d7a65d02 •
