Echo: linux: security update to 6.1.187-1

critical Tenable Self-Hosted Container Security Plugin ID 464602

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: iomap: adjust read range correctly for
 non-block-aligned positions iomap_adjust_read_range() assumes that the position and length passed in are
 block-aligned. This is not always the case however, as shown in the syzbot generated case for erofs. This
 causes too many bytes to be skipped for uptodate blocks, which results in returning the incorrect position
 and length to read in. If all the blocks are uptodate, this underflows length and returns a position
 beyond the folio. Fix the calculation to also take into account the block offset when calculating how many
 bytes can be skipped for uptodate blocks. (CVE-2025-68794)

Solution

Update the linux library and its related packages to version 6.1.187-1 or later.
