CVE-2026-45949

CVE-2026-45949 details from connected OSV/NVD entries confirm a race in the Linux kernel hwrng core where concurrent unregister/start calls may cause use-after-free due to hwrng_fill not being cleared reliably. The patch serializes access with rng_mutex, moves cleanup to a work_struct, and conver...

CVE-2026-45949 hwrng: core - use RCU and work_struct to fix race condition

In the Linux kernel, the following vulnerability has been resolved: hwrng: core - use RCU and workstruct to fix race condition Currently, hwrngfill is not cleared until the hwrngfillfn thread exits. Since hwrngunregister reads hwrngfill outside the rngmutex lock, a concurrent hwrngunregister may...

CVE-2026-45919 sched/rt: Skip currently executing CPU in rto_next_cpu()

In the Linux kernel, the following vulnerability has been resolved: sched/rt: Skip currently executing CPU in rtonextcpu CPU0 becomes overloaded when hosting a CPU-bound RT task, a non-CPU-bound RT task, and a CFS task stuck in kernel space. When other CPUs switch from RT to non-RT tasks, RT load...

CVE-2026-45856

The CVE-2026-45856 issue affects the Linux kernel's RDMA/uverbs subsystem, specifically ib_uverbs_post_send. The vulnerability arises when cmd.wqe_size from userspace is not validated before kmalloc and using the allocated memory as struct ib_uverbs_send_wr, allowing an out-of-bounds read of kern...

CVE-2026-45855

The CVE-2026-45855 issue affects the Linux kernel’s libata-scsi component, where NCQ command traffic could starve non-NCQ commands in multi-queue hosts. Root cause: mixing NCQ and non-NCQ can delay non-NCQ execution when NCQ is in-flight. The fix implements forward progress for non-NCQ commands b...
