Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 459093

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: Clamp HDMI HDCP2
 rx_id_list read to buffer size [Why & How] During HDCP 2.x repeater authentication over HDMI, the driver
 reads the sink's RxStatus register and extracts a 10-bit message size field (max value 1023). This value
 is used as the read length for the ReceiverID list without being clamped to the size of the destination
 buffer rx_id_list[177]. A malicious HDMI repeater could advertise a message size larger than the buffer,
 causing an out-of-bounds write during the I2C read. Clamp the read length in mod_hdcp_read_rx_id_list() to
 the size of the rx_id_list buffer, matching the approach already used in the DP branch. (cherry picked
 from commit 229212219e4247d9486f8ba41ef087358490be09) (CVE-2026-53137)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
