Echo: linux: security update to 6.1.180-1

medium Tenable Self-Hosted Container Security Plugin ID 465659

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: module: decompress: check return value
 of module_extend_max_pages() module_extend_max_pages() calls kvrealloc() internally and returns -ENOMEM on
 allocation failure. The return value is never checked. If the initial allocation fails, info->pages
 remains NULL and info->max_pages remains 0. Subsequent calls to module_get_next_page() will attempt to
 dynamically grow the array by calling module_extend_max_pages(info, 0) since info->used_pages is 0. This
 results in kvrealloc(NULL, 0) returning ZERO_SIZE_PTR, which is treated as a success, leading to a
 dereference of ZERO_SIZE_PTR and a kernel oops. Fix: add the missing error check after
 module_extend_max_pages() and return immediately on failure. This matches the pattern used by every other
 kvrealloc() caller in the module loading path. [Sami: Corrected the analysis in the commit message.]
 (CVE-2026-64297)

Solution

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