CVE-2024-36018

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nouveau/uvmm: corrige los cálculos de addr/range para operaciones de reasignación dEQP-VK.sparse_resources.image_rebind.2d_array.r64i.128_128_8 estaba provocando una operación de reasignación como la siguiente. OP_REMAP: Prev: 0000003FFED0000 00000000000F0000 0000000000A5ABD18A 0000000000000000 OP_REMAP: SIGUIEN 0000000000000E0000 Esto dio como resultado una operación de UNMAP desde 0x3fffed0000+0xf0000, 0x100000, que corrompía los pagetables y se agotaba el núcleo. Corrige los cálculos de rango anterior + desasignar para usar inicio/fin y volver a asignar a dirección/rango.

In the Linux kernel, the following vulnerability has been resolved: nouveau/uvmm: fix addr/range calcs for remap operations dEQP-VK.sparse_resources.image_rebind.2d_array.r64i.128_128_8 was causing a remap operation like the below. op_remap: prev: 0000003fffed0000 00000000000f0000 00000000a5abd18a 0000000000000000 op_remap: next: op_remap: unmap: 0000003fffed0000 0000000000100000 0 op_map: map: 0000003ffffc0000 0000000000010000 000000005b1ba33c 00000000000e0000 This was resulting in an unmap operation from 0x3fffed0000+0xf0000, 0x100000 which was corrupting the pagetables and oopsing the kernel. Fixes the prev + unmap range calcs to use start/end and map back to addr/range.

It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
