CVE-2026-90378

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt792x: Fix memory leak in SDIO TX path When txprepareskb returns an error in the SDIO TX path, the skb is not freed, leading to a memory leak. This can occur when zero-length frames such as WNM NULL frames are droppe...

CVE-2026-90378

CVE-2026-90378 affects the Linux kernel 's mt76/mt792x WiFi driver in its SDIO TX path . The root cause is a memory leak : when tx_prepare_skb() returns an error, the socket buffer (skb) is not freed. This can be triggered when zero-length frames (such as WNM NULL frames) are dropped to prevent p...

CVE-2026-90090

This CVE affects the Linux kernel Bluetooth btmtksdio driver. In the TX path, btmtksdio_tx_packet() rounds the transfer size up to the SDIO block size of 256 bytes but passes the raw SKB buffer to sdio_writesb(). Since only skb->len bytes hold actual packet data, the host controller reads up t...

CVE-2026-15923

The Zephyr SDIO subsystem function sdioiorwextendedhelper in subsys/sd/sdio.c finishes transfers with a byte-I/O loop that uses size = MINremaining, func-cis.maxblksize as the per-iteration step. The value func-cis.maxblksize is decoded directly from the SDIO card's CIS FUNCE tuple in sdiodecodec...

CVE-2026-15923 Infinite loop denial of service in Zephyr SDIO byte-I/O from a card-supplied zero max_blk_size

CVE-2026-15923

CVE-2026-15923 is a denial-of-service vulnerability in the Zephyr RTOS SDIO subsystem. The function sdio_io_rw_extended_helper() in subsys/sd/sdio.c uses func->cis.max_blk_size—decoded from a card's CIS FUNCE tuple without validation —as the per-iteration step in a byte-I/O loop. When a card r...
