Chainguard: linux-desktop-7.2-bootc: security update to 7.2.7-r0

high Tenable Self-Hosted Container Security Plugin ID 474670

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: bcmasp: clear txcb->last before
 writing each descriptor bcmasp_xmit() only wrote txcb->last = true for the final fragment of an SKB; non-
 final fragments left the field untouched. If a descriptor slot was reused while it still held a stale true
 from a previous SKB (possible when tx_spb_ring_full() underreported fullness), bcmasp_tx_reclaim() would
 see last == true mid-SKB and call dev_consume_skb_any() prematurely, freeing the sk_buff while its
 remaining fragments were still in flight. Unconditionally clear txcb->last before the conditional set so
 every descriptor slot starts from a known false state regardless of what a prior transmission left behind.
 (CVE-2026-98052)

Solution

Update the linux-desktop-7.2-bootc library and its related packages to version 7.2.7-r0 or later.
