CVE-2022-50541 dmaengine: ti: k3-udma: Reset UDMA_CHAN_RT byte counters to prevent overflow

In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma: Reset UDMACHANRT byte counters to prevent overflow UDMACHANRTBCNTREG stores the real-time channel bytecount statistics. These registers are 32-bit hardware counters and the driver uses these counters to...

kernel: dmaengine: ti: k3-udma: Reset UDMA_CHAN_RT byte counters to prevent overflow

A counter-overflow flaw was found in the Linux kernel Texas Instruments K3 Universal Direct Memory Access UDMA driver. During long data transfers exceeding four gigabytes, the hardware byte-count registers could wrap and misreport progress, causing the transfer to hang indefinitely. A local user...
