CVE-2024-26976

In the Linux kernel, the following vulnerability has been resolved: KVM: Always flush async PF workqueue when vCPU is being destroyed Always flush the per-vCPU async PF workqueue when a vCPU is clearing its completion queue, e.g. when a VM and all its vCPUs is being destroyed. KVM must ensure tha...

kernel: Linux kernel: Privilege escalation via out-of-bounds write in RDMA/siw

A flaw was identified in the Linux kernel RDMA siw implementation where an undefined opcode value could be used during immediate work request flushing while in an error state. The send queue element opcode was not correctly set, which could lead to an out-of-bounds access when mapping between the...

kernel: RDMA/irdma: Fix data race on CQP request done

A race condition was identified in the RDMA/irdma subsystem of the Linux kernel affecting how completion queue pair CQP requests are processed. The cqprequest-requestdone memory location is accessed without appropriate synchronization in the irdmahandlecqpop function while it is concurrently...

kernel: RDMA/irdma: Fix data race on CQP completion stats

The Linux kernel contains a race condition vulnerability in its RDMA/irdma subsystem, where completion queue pair CQP completion statistics are read concurrently without adequate synchronization while being updated on another CPU. Under certain workloads, a lack of atomic operations and improper...

kernel: net/mlx5e: xsk: Fix crash on regular rq reactivation

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix crash on regular rq reactivation When the regular rq is reactivated after the XSK socket is closed it could be reading stale cqes which eventually corrupts the rq. This leads to no more traffic being received ...
