Echo: linux: security update to 6.1.153-1

medium Tenable Cloud Security Plugin ID 461364

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: parisc: Revise gateway LWS calls to
 probe user read access We use load and stbys,e instructions to trigger memory reference interruptions
 without writing to memory. Because of the way read access support is implemented, read access
 interruptions are only triggered at privilege levels 2 and 3. The kernel and gateway page execute at
 privilege level 0, so this code never triggers a read access interruption. Thus, it is currently possible
 for user code to execute a LWS compare and swap operation at an address that is read protected at
 privilege level 3 (PRIV_USER). Fix this by probing read access rights at privilege level 3 and branching
 to lws_fault if access isn't allowed. (CVE-2025-39715)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
