UBUNTU-CVE-2026-45919

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...

AZL-59423 CVE-2024-58083 affecting package kernel for versions less than 5.15.180.1-1

In the Linux kernel, the following vulnerability has been resolved: KVM: Explicitly verify target vCPU is online in kvmgetvcpu Explicitly verify the target vCPU is fully online prior to clamping the index in kvmgetvcpu. If the index is "bad", the nospec clamping will generate '0', i.e. KVM will...

kernel: srcu: Delegate work to the boot cpu if using SRCU_SIZE_SMALL

A synchronization flaw was found in the Linux kernel Sleepable Read-Copy-Update SRCU implementation. The subsystem assumed that central processing unit CPU 0 was always online. On systems where CPU 0 is offline, such as crash-kernel configurations using a different boot CPU, SRCU work could be...

CVE-2023-5370

On CPU 0 the check for the SMCCC workaround is called before SMCCC support has been initialized. This resulted in no speculative execution workarounds being installed on CPU 0...
