Every so often pt->memory->ptrs is NULL. This     ptrs ptr is set in the nv50_instobj_acquire called from nvkm_kmap. If Thread A and Thread B both get to     nv50_instobj_acquire around the same time, and Thread A hits the refcount_set line, and in lockstep thread     B succeeds at refcount_inc_not_zero, there is a chance the ptrs value won't have been stored since     refcount_set is unordered. Force a memory barrier here, I picked smp_mb, since we want it on all CPUs and     it's write followed by a read. v2: use paired smp_rmb/smp_wmb. (CVE-2024-26984)

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix use-after-free bugs     caused by sco_sock_timeout When the sco connection is established and then, the sco socket is releasing,     timeout_work will be scheduled to judge whether the sco disconnection is timeout. The sock will be     deallocated later, but it is dereferenced again in sco_sock_timeout. As a result, the use-after-free bugs     will happen.

  - In the Linux kernel, the following vulnerability has been resolved: firewire: nosy: ensure user_length is     taken into account when fetching packet contents Ensure that packet_buffer_get respects the user_length     provided. If the length of the head packet exceeds the user_length, packet_buffer_get will now return 0 to     signify to the user that no data were read and a larger buffer size is required. Helps prevent user space     overflows. (CVE-2024-27401)

  - In the Linux kernel, the following vulnerability has been resolved: riscv: process: Fix kernel gp leakage     childregs represents the registers which are active for the new thread in user context. For a kernel     thread, childregs->gp is never used since the kernel gp is not touched by switch_to. For a user mode     helper, the gp value can be observed in user space after execve or possibly by other means. [From the     email thread] The /* Kernel thread */ comment is somewhat inaccurate in that it is also used for     user_mode_helper threads, which exec a user process, e.g. /sbin/init or when /proc/sys/kernel/core_pattern     is a pipe. Such threads do not have PF_KTHREAD set and are valid targets for ptrace etc. even before they     exec. childregs is the *user* context during syscall execution and it is observable from userspace in at     least five ways: 1. kernel_execve does not currently clear integer registers, so the starting register     state for PID 1 and other user processes started by the kernel has sp = user stack, gp = kernel
    __global_pointer$, all other integer registers zeroed by the memset in the patch comment. This is a bug in     its own right, but I'm unwilling to bet that it is the only way to exploit the issue addressed by this     patch. 2. ptrace(PTRACE_GETREGSET): you can PTRACE_ATTACH to a user_mode_helper thread before it execs,     but ptrace requires SIGSTOP to be delivered which can only happen at user/kernel boundaries. 3.
    /proc/*/task/*/syscall: this is perfectly happy to read pt_regs for user_mode_helpers before the exec     completes, but gp is not one of the registers it returns. 4. PERF_SAMPLE_REGS_USER: LOCKDOWN_PERF normally     prevents access to kernel addresses via PERF_SAMPLE_REGS_INTR, but due to this bug kernel addresses are     also exposed via PERF_SAMPLE_REGS_USER which is permitted under LOCKDOWN_PERF. I have not attempted to     write exploit code. 5. Much of the tracing infrastructure allows access to user registers. I have not     attempted to determine which forms of tracing allow access to user registers without already allowing     access to kernel registers. (CVE-2024-35871)
