Echo: linux: security update to 6.1.180-1

medium Tenable Cloud Security Plugin ID 462781

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: iio: accel: bmc150: clamp the device-
 reported FIFO frame count __bmc150_accel_fifo_flush() copies the number of samples the device reports in
 its hardware FIFO into an on-stack buffer u16 buffer[BMC150_ACCEL_FIFO_LENGTH * 3]; which is sized for at
 most BMC150_ACCEL_FIFO_LENGTH (32) samples. The frame count is read from the FIFO_STATUS register and only
 masked to its 7 valid bits: count = val & 0x7F; so it can be 0..127. The only other limit applied to it is
 the optional caller-supplied sample budget: if (samples && count > samples) count = samples; which does
 not constrain count on the flush-all path (samples == 0), and leaves it well above 32 whenever samples is
 larger. count samples are then transferred into buffer[]: bmc150_accel_fifo_transfer(data, (u8 *)buffer,
 count); bmc150_accel_fifo_transfer() reads count * 6 bytes through regmap, so a malfunctioning, malicious
 or counterfeit accelerometer (or an attacker tampering with the I2C/SPI bus) that reports up to 127 frames
 writes up to 762 bytes into the 192-byte buffer: a stack out-of-bounds write of up to 570 bytes that
 clobbers the stack canary, saved registers and the return address. Clamp count to
 BMC150_ACCEL_FIFO_LENGTH, the number of samples buffer[] is sized for, before the transfer, mirroring the
 watermark clamp already done in bmc150_accel_set_watermark(). A well-formed flush reports at most
 BMC150_ACCEL_FIFO_LENGTH frames, so legitimate devices are unaffected. (CVE-2026-64504)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
