CVE-2026-90378 wifi: mt76: mt792x: Fix memory leak in SDIO TX path

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-2026-90090

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

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...
