Echo: linux: security update to 6.1.158-1

high Tenable Self-Hosted Container Security Plugin ID 461144

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: nfc: nci: Add parameter
 validation for packet data Syzbot reported an uninitialized value bug in nci_init_req, which was
 introduced by commit 5aca7966d2a7 ("Merge tag 'perf-tools-fixes-for-v6.17-2025-09-16' of
 git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools"). This bug arises due to very limited and
 poor input validation that was done at nic_valid_size(). This validation only validates the skb->len
 (directly reflects size provided at the userspace interface) with the length provided in the buffer itself
 (interpreted as NCI_HEADER). This leads to the processing of memory content at the address assuming the
 correct layout per what opcode requires there. This leads to the accesses to buffer of `skb_buff->data`
 which is not assigned anything yet. Following the same silent drop of packets of invalid sizes at
 `nic_valid_size()`, add validation of the data in the respective handlers and return error values in case
 of failure. Release the skb if error values are returned from handlers in `nci_nft_packet` and effectively
 do a silent drop Possible TODO: because we silently drop the packets, the call to `nci_request` will be
 waiting for completion of request and will face timeouts. These timeouts can get excessively logged in the
 dmesg. A proper handling of them may require to export `nci_request_cancel` (or propagate error handling
 from the nft packets handlers). (CVE-2025-40043)

Solution

Update the linux library and its related packages to version 6.1.158-1 or later.
