CVE-2026-53170

Concrete details confirm a vulnerability in the Linux kernel accel/ethosu driver: cmd_state_init() leaves dma->len at U64_MAX to signal uninitialized length, and dma_length() can wrap a positive stride to a small value, causing a bypass of region checks in ethosu_job.c when userspace omits the...

CVE-2026-8720: Improper Validation of Integrity Check Value

wcBlake2bHmacFinal and wcBlake2sHmacFinal discard the message when the key length exceeds the block size, producing a MAC that is independent of the input. When the supplied key is longer than the BLAKE2 block size the key-hashing branch reinitialized the running hash state, discarding the...
