Suna before 0.9.102 contains a broken access control vulnerability in the message queue API that allows authenticated attackers to access and manipulate queue resources belonging to other users by exploiting missing ownership and account isolation checks. Attackers can read pending prompt queues of all users, read or delete individual sessions, and inject arbitrary prompts into another user's sess…

In the Linux kernel, the following vulnerability has been resolved: pwrseq: core: fix use-after-free in pwrseq_debugfs_seq_next() pwrseq_debugfs_seq_next() declares 'next' with __free(put_device), which causes put_device() to be called on the returned pointer when the variable goes out of scope. This results in a use-after-free since the seq_file framework receives a pointer whose reference has…

In the Linux kernel, the following vulnerability has been resolved: sched_ext: Avoid UAF in scx_root_enable_workfn() init failure path In scx_root_enable_workfn(), put_task_struct(p) is called before scx_error() dereferences p->comm and p->pid. If the iterator's reference is the last drop, the task is freed synchronously and the deref becomes a UAF. Move put_task_struct() past scx_error().
