Echo: linux: security update to 6.12.43-1

high Tenable Cloud Security Plugin ID 464486

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: staging: media: atomisp: Fix stack
 buffer overflow in gmin_get_var_int() When gmin_get_config_var() calls efi.get_variable() and the EFI
 variable is larger than the expected buffer size, two behaviors combine to create a stack buffer overflow:
 1. gmin_get_config_var() does not return the proper error code when efi.get_variable() fails. It returns
 the stale 'ret' value from earlier operations instead of indicating the EFI failure. 2. When
 efi.get_variable() returns EFI_BUFFER_TOO_SMALL, it updates *out_len to the required buffer size but
 writes no data to the output buffer. However, due to bug #1, gmin_get_var_int() believes the call
 succeeded. The caller gmin_get_var_int() then performs: - Allocates val[CFG_VAR_NAME_MAX + 1] (65 bytes)
 on stack - Calls gmin_get_config_var(dev, is_gmin, var, val, &len) with len=64 - If EFI variable is >64
 bytes, efi.get_variable() sets len=required_size - Due to bug #1, thinks call succeeded with
 len=required_size - Executes val[len] = 0, writing past end of 65-byte stack buffer This creates a stack
 buffer overflow when EFI variables are larger than 64 bytes. Since EFI variables can be controlled by
 firmware or system configuration, this could potentially be exploited for code execution. Fix the bug by
 returning proper error codes from gmin_get_config_var() based on EFI status instead of stale 'ret' value.
 The gmin_get_var_int() function is called during device initialization for camera sensor configuration on
 Intel Bay Trail and Cherry Trail platforms using the atomisp camera stack. (CVE-2025-38585)

Solution

Update the linux library and its related packages to version 6.12.43-1 or later.
