CVE-2022-49441

CVE-2022-49441 relates to a Linux kernel deadlock in tty handling. The root cause is a potential deadlock when kmalloc() path could trigger a printk() while holding tty_port->lock, enabling a cycle with console ownership locks. The described failing scenario involves multiple CPUs acquiring po...

CVE-2022-49433 RDMA/hfi1: Prevent use of lock before it is initialized

In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Prevent use of lock before it is initialized If there is a failure during probe of hfi1 before the sdmamaplock is initialized, the call to hfi1freedevdata will attempt to use a lock that has not been initialized. If th...

CVE-2022-49433

The CVE-2022-49433 entry is confirmed with concrete details in connected advisories: in the Linux kernel RDMA/hfi1 driver, a path may call hfi1_free_devdata() with sdma_map_lock uninitialized if probe of hfi1 fails before sdma_map_lock is set up. This could lead to locking operations being perfor...
