kernel: perf/arm_dmc620: Fix hotplug callback leak in dmc620_pmu_init()

A resource leak flaw was found in the ARM DMC-620 PMU driver. If platformdriverregister fails during module initialization, the CPU hotplug callback registered earlier is not removed, leaving a dangling callback...

kernel: net/sched: flower: fix filter idr initialization

A flaw was found in the Linux kernel’s networking traffic control flower classifier. The initialization of the filter IDR was moved too early in the flchange path, allowing concurrent access by multiple users while the structure was still in an inconsistent state. Under certain conditions, this...

kernel: Linux kernel: NULL pointer dereference in drm/amdkfd leads to Denial of Service

A flaw was found in the Linux kernel. A local user could trigger a NULL pointer dereference within the drm/amdkfd component during error handling in the kfdprocessdeviceinitvm function. This vulnerability, a type of memory corruption, can lead to a system crash. Successful exploitation results in...

kernel: mptcp: fix UaF in listener shutdown

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix UaF in listener shutdown As reported by Christoph after having refactored the passive socket initialization, the mptcp listener shutdown path is prone to an UaF issue. BUG: KASAN: use-after-free in...

kernel: iommu/vt-d: Clean up si_domain in the init_dmars() error path

A memory leak flaw was found in the Linux kernel's Intel VT-d IOMMU driver in the initialization error path. A local user can trigger this issue when the initdmars function fails during IOMMU setup, causing the sidomain memory to remain allocated without being freed. This results in a permanent...

kernel: drm/amdkfd: Add sync after creating vram bo

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Add sync after creating vram bo There will be data corruption on vram allocated by svm if the initialization is not complete and application is writting on the memory. Adding sync to wait for the initialization...

kernel: drm: Fix potential null-ptr-deref due to drmm_mode_config_init()

In the Linux kernel, the following vulnerability has been resolved: drm: Fix potential null-ptr-deref due to drmmmodeconfiginit drmmmodeconfiginit will call drmmodecreatestandardproperties and won't check the ret value. When drmmodecreatestandardproperties failed due to alloc, property will be a...

kernel: perf/smmuv3: Fix hotplug callback leak in arm_smmu_pmu_init()

A resource-handling flaw was found in the Linux kernel performance monitoring driver for ARM System Memory Management Unit version 3 in the way hotplug callbacks are registered during driver initialization. If driver registration fails, previously added CPU hotplug callbacks are not removed,...

kernel: floppy: Fix memory leak in do_floppy_init()

In the Linux kernel, the following vulnerability has been resolved: floppy: Fix memory leak in dofloppyinit A memory leak was reported when floppyallocdisk failed in dofloppyinit. unreferenced object 0xffff888115ed25a0 size 8: comm "modprobe", pid 727, jiffies 4295051278 age 25.529s hex dump firs...

kernel: net: wwan: iosm: fix NULL pointer dereference when removing device

In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix NULL pointer dereference when removing device In suspend and resume cycle, the removal and rescan of device ends up in NULL pointer dereference. During driver initialization, if the ipcimemwwanchannelinit fai...

kernel: nfsd: move init of percpu reply_cache_stats counters back to nfsd_init_net

A flaw was identified in the NFS server nfsd implementation in the Linux kernel where the initialization of the per-CPU replycachestats counters was relocated incorrectly in the code path. This change can lead to use of uninitialized per-CPU statistical counters during NFS request handling when t...

kernel: drm/amd/display: fix mapping to non-allocated address

An out-of-bounds array access was found in the AMD display driver in the Linux kernel. The driver allocates GPIO registers using incorrect bounds, leading to access of non-allocated memory addresses. This could cause kernel memory corruption or crashes during display initialization...

kernel: Kernel (iommufd): Information Disclosure via uninitialized memory padding

A flaw was found in the kernel. A local attacker could exploit this by triggering a missing zero initialization in the iommufd component when copying vfioiommutype1info to user space. This could lead to the disclosure of sensitive information from uninitialized memory padding...

kernel: dm stats: check for and propagate alloc_percpu failure

In the Linux kernel, the following vulnerability has been resolved: dm stats: check for and propagate allocpercpu failure Check allocprecpu's return value and return an error from dmstatsinit if it fails. Update allocdev to fail if dmstatsinit does. Otherwise, a NULL pointer dereference will occu...

kernel: ixgbevf: Fix resource leak in ixgbevf_init_module()

In the Linux kernel, the following vulnerability has been resolved: ixgbevf: Fix resource leak in ixgbevfinitmodule ixgbevfinitmodule won't destroy the workqueue created by createsinglethreadworkqueue when pciregisterdriver failed. Add destroyworkqueue in fail path to prevent the resource leak...

kernel: RDMA/rxe: Fix "kernel NULL pointer dereference" error

A NULL pointer dereference vulnerability was found in the RXE Soft-RoCE RDMA driver in the Linux kernel. When rxequeueinit fails during queue pair initialization in rxeqpinitreq, the task function and argument pointers qp-req.task.func and qp-req.task.arg remain uninitialized. The cleanup functio...

kernel: Linux kernel KVM: Denial of Service due to incorrect kvm_arm_init failure handling in finalize_pkvm

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architectures. This vulnerability arises from a lack of synchronization between the finalizepkvm and kvmarminit initialization calls. A local attacker with low privileges could exploit this by triggering a scenario...
