CVE-2026-72141 i2c: imx: fix locked bus on SMBus block-read of 0 (IRQ)

In the Linux kernel, the following vulnerability has been resolved: i2c: imx: fix locked bus on SMBus block-read of 0 IRQ SMBus 3.1 6.5.7 allows a Block Read byte count of 0, but the interrupt-driven block-read state machine rejects it as -EPROTO. Worse, it returns without a NACK+STOP: the next...

CVE-2026-72141

CVE-2026-72141 covers a Linux kernel issue in the i2c/imx SMBus path where a Block Read with a count of 0 could cause the bus to stay locked. The vulnerability arises because the interrupt-driven state machine incorrectly handles -EPROTO for a zero-byte block read, failing to issue a NACK+STOP an...
