Echo: linux: security update to 6.1.177-1

high Tenable Self-Hosted Container Security Plugin ID 460389

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/amd/display: Bound VBIOS record-
chain walk loops [Why & How] All record-chain walk loops in bios_parser.c and bios_parser2.c use for(;;)
and only terminate on a 0xFF record_type sentinel or zero record_size. A malformed VBIOS image missing the
terminator record causes unbounded iteration at probe time, potentially hundreds of thousands of
iterations with record_size=1. In the final iterations near the BIOS image boundary, struct casts beyond
the 2-byte header validated by GET_IMAGE can also read out of bounds. Cap all 14 record-chain walk loops
to BIOS_MAX_NUM_RECORD (256) iterations. The atombios.h defines up to 22 distinct record types and
atomfirmware.h has 13. Assuming an average of less than 10 records per type (which is reasonable since
most are connector- based) 256 is a generous upper bound. (cherry picked from commit
95700a3d660287ed657d6892f7be9ffc0e294a93) (CVE-2026-53138)
