Echo: linux: security update to 6.1.133-1

medium Tenable Cloud Security Plugin ID 462345

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix use-after-free bug The
 bug can be triggered by sending a single amdgpu_gem_userptr_ioctl to the AMDGPU DRM driver on any ASICs
 with an invalid address and size. The bug was reported by Joonkyo Jung <[email protected]>. For
 example the following code: static void Syzkaller1(int fd) { struct drm_amdgpu_gem_userptr arg; int ret;
 arg.addr = 0xffffffffffff0000; arg.size = 0x80000000; /*2 Gb*/ arg.flags = 0x7; ret = drmIoctl(fd,
 0xc1186451/*amdgpu_gem_userptr_ioctl*/, &arg); } Due to the address and size are not valid there is a
 failure in amdgpu_hmm_register->mmu_interval_notifier_insert->__mmu_interval_notifier_insert->
 check_shl_overflow, but we even the amdgpu_hmm_register failure we still call amdgpu_hmm_unregister into
 amdgpu_gem_object_free which causes access to a bad address. The following stack is below when the issue
 is reproduced when Kazan is enabled: [ +0.000014] Hardware name: ASUS System Product Name/ROG STRIX B550-F
