kernel: procfs: fix missing RCU protection when reading real_parent in do_task_stat()

A flaw was found in the Linux kernel's procfs component. When reading /proc/pid/stat, the dotaskstat function accesses task-realparent without proper Read-Copy-Update RCU protection. This missing protection creates a race condition, which can lead to a Use-After-Free UAF vulnerability. A local...

kernel: RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()

A flaw was found in the Linux kernel's RDMA/mlx4 component. This vulnerability arises from the incorrect use of Read-Copy Update RCU in the mlx4srqevent function. An attacker could potentially trigger an event before the srq object is fully initialized, leading to a system crash. This could resul...

CVE-2026-52975

A flaw was found in the Linux kernel's bonding 3ad module. This vulnerability is due to a data-race condition caused by improper Read-Copy-Update RCU implementation in the port-aggregator component. An attacker could potentially exploit this to cause system instability or unexpected behavior...

CVE-2026-53083

A flaw was found in the Linux kernel. A missing condresched in the bpffdarraymapclear loop, specifically when handling BPF Berkeley Packet Filter PROGARRAY maps with numerous entries, can lead to an RCU Read-Copy Update stall. This can result in a Denial of Service DoS under heavy system load, as...
