Echo: linux: security update to 6.12.90-1

medium Tenable Cloud Security Plugin ID 463881

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/amdkfd: Clear VRAM on allocation
 to prevent stale data exposure KFD VRAM allocations set AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE but not
 AMDGPU_GEM_CREATE_VRAM_CLEARED, leaving freshly allocated VRAM with stale data from prior use observable
 by compute kernels. The GEM ioctl path already sets VRAM_CLEARED for all userspace allocations via
 amdgpu_gem_create_ioctl() and amdgpu_mode_dumb_create(). The KFD path was missing this flag, allowing
 stale page table remnants to leak into user buffers. This causes crashes in RCCL P2P transport where non-
 zero data in ptrExchange/head/tail fields corrupts the protocol handshake. (CVE-2026-46229)

Solution

Update the linux library and its related packages to version 6.12.90-1 or later.
