CVE-2026-23133 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: fix dma_free_coherent() pointer dma_alloc_coherent() allocates a DMA mapped buffer and stores the addresses in XXX_unaligned fields. Those should be reused when freeing the buffer rather than the aligned addresses.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
