Echo: linux: security update to 6.1.180-1

medium Tenable Self-Hosted Container Security Plugin ID 458072

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: Drop the lock in
 skb_may_tx_timestamp() skb_may_tx_timestamp() may acquire sock::sk_callback_lock. The lock must not be
 taken in IRQ context, only softirq is okay. A few drivers receive the timestamp via a dedicated interrupt
 and complete the TX timestamp from that handler. This will lead to a deadlock if the lock is already
 write-locked on the same CPU. Taking the lock can be avoided. The socket (pointed by the skb) will remain
 valid until the skb is released. The ->sk_socket and ->file member will be set to NULL once the user
 closes the socket which may happen before the timestamp arrives. If we happen to observe the pointer while
 the socket is closing but before the pointer is set to NULL then we may use it because both pointer (and
 the file's cred member) are RCU freed. Drop the lock. Use READ_ONCE() to obtain the individual pointer.
 Add a matching WRITE_ONCE() where the pointer are cleared. (CVE-2026-43216)

Solution

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