Official Description
In the Linux kernel, the following vulnerability has been resolved:
net: wan/fsl_ucc_hdlc: Fix dma_free_coherent() in uhdlc_memclean()
The priv->rx_buffer and priv->tx_buffer are alloc'd together as
contiguous buffers in uhdlc_init() but freed as two buffers in
uhdlc_memclean().
Change the cleanup to only call dma_free_coherent() once on the whole
buffer.
Technical Analysis
CVE-2026-43149 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
