Echo: linux: security update to 6.12.10-1

medium Tenable Cloud Security Plugin ID 464717

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: rds: sysctl: rds_tcp_{rcv,snd}buf:
 avoid using current->nsproxy As mentioned in a previous commit of this series, using the 'net' structure
 via 'current' is not recommended for different reasons: - Inconsistency: getting info from the
 reader's/writer's netns vs only from the opener's netns. - current->nsproxy can be NULL in some cases,
 resulting in an 'Oops' (null-ptr-deref), e.g. when the current task is exiting, as spotted by syzbot [1]
 using acct(2). The per-netns structure can be obtained from the table->data using container_of(), then the
 'net' one can be retrieved from the listen socket (if available). (CVE-2025-21635)

Solution

Update the linux library and its related packages to version 6.12.10-1 or later.
