Echo: linux: security update to 6.7.7-1

medium Tenable Cloud Security Plugin ID 458803

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: net/sched: act_mirred: use the backlog
for mirred ingress The test Davide added in commit ca22da2fbd69 ("act_mirred: use the backlog for nested
calls to mirred ingress") hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv ->
tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that
if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which
generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks
is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress ->
ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the
backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround
does not seem to address the issue. (CVE-2024-26740)

Solution

Update the linux library and its related packages to version 6.7.7-1 or later.
