Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 455170

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: USB: serial: io_ti: fix heap overflow
 in get_manuf_info() get_manuf_info() reads le16_to_cpu(rom_desc->Size) bytes from the device I2C EEPROM
 into a buffer allocated with kmalloc_obj(), which is sizeof(struct edge_ti_manuf_descriptor) = 10 bytes.
 The Size field comes from the device and is only validated (in check_i2c_image()) to make sure the
 descriptor fits within TI_MAX_I2C_SIZE (16384 bytes), not against the destination buffer size. A malicious
 USB device can therefore set Size to any value up to 16377, causing a heap overflow of up to 16367 bytes
 when plugged into a host running this driver. valid_csum() is called after read_rom() and also iterates
 buffer[0..Size-1], compounding the out-of-bounds access. Fix by rejecting descriptors with unexpected
 length before calling read_rom(). [ johan: amend commit message; also check for short descriptors ]
 (CVE-2026-53196)

Solution

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