Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the btrfssetitemkeysafe function discovering duplicate keys, which causes a crash...

CVE-2024-32936 media: ti: j721e-csi2rx: Fix races while restarting DMA

In the Linux kernel, the following vulnerability has been resolved: media: ti: j721e-csi2rx: Fix races while restarting DMA After the frame is submitted to DMA, it may happen that the submitted list is not updated soon enough, and the DMA callback is triggered before that. This can lead to kernel...
