https://notcve.org/view.php?id=CVE-2024-46834
In the Linux kernel, the following vulnerability has been resolved: ethtool: fail closed if we can't get max channel used in indirection tables Commit 0d1b7d6c9274 ("bnxt: fix crashes when reducing ring count with active RSS contexts") proves that allowing indirection table to contain channels with out of bounds IDs may lead to crashes. Currently the max channel check in the core gets skipped if driver can't fetch the indirection table or when we can't allocate memory. Both of those conditions should be extremely rare but if they do happen we should try to be safe and fail the channel change. • https://git.kernel.org/stable/c/101737d8b88dbd4be6010bac398fe810f1950036 https://git.kernel.org/stable/c/2899d58462ba868287d6ff3acad3675e7adf934f •

In the Linux kernel, the following vulnerability has been resolved: net: hns3: void array out of bound when loop tnl_num When query reg inf of SSU, it loops tnl_num times. However, tnl_num comes from hardware and the length of array is a fixed value. To void array out of bound, make sure the loop time is not greater than the length of array • https://git.kernel.org/stable/c/c33a9806dc806bcb4a31dc71fb06979219181ad4 https://git.kernel.org/stable/c/86db7bfb06704ef17340eeae71c832f21cfce35c •

CVSS: -EPSS: %CPEs: 7EXPL: 0CVE-2024-46830 – KVM: x86: Acquire kvm->srcu when handling KVM_SET_VCPU_EVENTS
https://notcve.org/view.php?id=CVE-2024-46830
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Acquire kvm->srcu when handling KVM_SET_VCPU_EVENTS Grab kvm->srcu when processing KVM_SET_VCPU_EVENTS, as KVM will forcibly leave nested VMX/SVM if SMM mode is being toggled, and leaving nested VMX reads guest memory. Note, kvm_vcpu_ioctl_x86_set_vcpu_events() can also be called from KVM_RUN via sync_regs(), which already holds SRCU. I.e. trying to precisely use kvm_vcpu_srcu_read_lock() around the problematic SMM code would cause problems. Acquiring SRCU isn't all that expensive, so for simplicity, grab it unconditionally for KVM_SET_VCPU_EVENTS. ============================= WARNING: suspicious RCU usage 6.10.0-rc7-332d2c1d713e-next-vm #552 Not tainted ----------------------------- include/linux/kvm_host.h:1027 suspicious rcu_dereference_check() usage! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 1 lock held by repro/1071: #0: ffff88811e424430 (&vcpu->mutex){+.+.}-{3:3}, at: kvm_vcpu_ioctl+0x7d/0x970 [kvm] stack backtrace: CPU: 15 PID: 1071 Comm: repro Not tainted 6.10.0-rc7-332d2c1d713e-next-vm #552 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 Call Trace: <TASK> dump_stack_lvl+0x7f/0x90 lockdep_rcu_suspicious+0x13f/0x1a0 kvm_vcpu_gfn_to_memslot+0x168/0x190 [kvm] kvm_vcpu_read_guest+0x3e/0x90 [kvm] nested_vmx_load_msr+0x6b/0x1d0 [kvm_intel] load_vmcs12_host_state+0x432/0xb40 [kvm_intel] vmx_leave_nested+0x30/0x40 [kvm_intel] kvm_vcpu_ioctl_x86_set_vcpu_events+0x15d/0x2b0 [kvm] kvm_arch_vcpu_ioctl+0x1107/0x1750 [kvm] ? mark_held_locks+0x49/0x70 ? • https://git.kernel.org/stable/c/f7e570780efc5cec9b2ed1e0472a7da14e864fdb https://git.kernel.org/stable/c/080dbe7e9b86a0392d8dffc00d9971792afc121f https://git.kernel.org/stable/c/e302786233e6bc512986d007c96458ccf5ca21c7 https://git.kernel.org/stable/c/b4c0d89c92e957ecccce12e66b63875d0cc7af7e https://git.kernel.org/stable/c/fa297c33faefe51e10244e8a378837fca4963228 https://git.kernel.org/stable/c/939375737b5a0b1bf9b1e75129054e11bc9ca65e https://git.kernel.org/stable/c/ecdbe8ac86fb5538ccc623a41f88ec96c7168ab9 https://git.kernel.org/stable/c/4bcdd831d9d01e0fb64faea50732b59b2 •
CVSS: -EPSS: %CPEs: 14EXPL: 0CVE-2024-46829 – rtmutex: Drop rt_mutex::wait_lock before scheduling
https://notcve.org/view.php?id=CVE-2024-46829
In the Linux kernel, the following vulnerability has been resolved: rtmutex: Drop rt_mutex::wait_lock before scheduling rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the good case it returns with the lock held and in the deadlock case it emits a warning and goes into an endless scheduling loop with the lock held, which triggers the 'scheduling in atomic' warning. Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning and dropping into the schedule for ever loop. [ tglx: Moved unlock before the WARN(), removed the pointless comment, massaged changelog, added Fixes tag ] • https://git.kernel.org/stable/c/3d5c9340d1949733eb37616abd15db36aef9a57c https://git.kernel.org/stable/c/95f9aded9436aa3ce714aeff3f45fcc1431df7d2 https://git.kernel.org/stable/c/ea018da95368adfb700689bd9842714f7c3db665 https://git.kernel.org/stable/c/1201613a70dd34bd347ba2970919b3f1d5fbfb4a https://git.kernel.org/stable/c/a2e64fcdc83c645813f7b93e4df291841ba7c625 https://git.kernel.org/stable/c/fb52f40e085ef4074f1335672cd62c1f832af13b https://git.kernel.org/stable/c/2b1f3807ed9cafb59c956ce76a05d25e67103f2e https://git.kernel.org/stable/c/432efdbe7da5ecfcbc0c2180cfdbab144 •
