medium Tenable Self-Hosted Container Security Plugin ID 474671

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: stmmac: fix dma mapping leak in
 stmmac_tso_xmit() In stmmac_tso_xmit(), if the DMA mapping of an skb fragment fails, the frame is dropped
 but the DMA mappings already created for the linear part and for the fragments mapped before the failure
 are never unmapped, leaking DMA mappings. Fix the leak by walking back over the descriptors used by the
 frame and releasing each of them with stmmac_free_tx_buffer(). Moreover, release the descriptors with
 stmmac_release_tx_desc() unmapping the DMA buffers. (CVE-2026-98131)

Solution

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