kernel: virtio-blk: Avoid use-after-free on suspend/resume

In the Linux kernel, the following vulnerability has been resolved: virtio-blk: Avoid use-after-free on suspend/resume hctx-userdata is set to vq in virtblkinithctx. However, vq is freed on suspend and reallocated on resume. So, hctx-userdata is invalid after resume, and it will cause...

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: clk: tegra20: Fix refcount leak in tegra20_clock_init

In the Linux kernel, the following vulnerability has been resolved: clk: tegra20: Fix refcount leak in tegra20clockinit offindmatchingnode returns a node pointer with refcount incremented, we should use ofnodeput on it when not need anymore. Add missing ofnodeput to avoid refcount leak...

kernel: media: dvb-usb: fix memory leak in dvb_usb_adapter_init()

In the Linux kernel, the following vulnerability has been resolved: media: dvb-usb: fix memory leak in dvbusbadapterinit Syzbot reports a memory leak in "dvbusbadapterinit". The leak is due to not accounting for and freeing current iteration's adapter-priv in case of an error. Currently if an err...

kernel: regulator: core: Use different devices for resource allocation and DT lookup

In the Linux kernel, the following vulnerability has been resolved: regulator: core: Use different devices for resource allocation and DT lookup Following by the below discussion, there's the potential UAF issue between regulator and mfd...

In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Fix memory leak in vkmsinit A memory leak was reported after the vkms module install failed. unreferenced object 0xffff88810bc28520 size 16: comm "modprobe", pid 9662, jiffies 4298009455 age 42.590s hex dump first 16...

kernel: Linux kernel: Denial of service in lontium-lt9611 GPU driver due to NULL pointer dereference

A flaw was found in the Linux kernel's lontium-lt9611 GPU driver. A local user with low privileges could trigger a NULL pointer dereference in the lt9611connectorinit function. This vulnerability can lead to a system crash, resulting in a Denial of Service DoS...

kernel: bpf: Skip task with pid=1 in send_signal_common()

In the Linux kernel, the following vulnerability has been resolved: bpf: Skip task with pid=1 in sendsignalcommon The following kernel panic can be triggered when a task with pid=1 attaches a prog that attempts to send killing signal to itself, also see 1 for more details: Kernel panic - not...

In the Linux kernel, the following vulnerability has been resolved: dmaengine: imx-sdma: Fix a possible memory leak in sdmatransferinit If the function sdmaloadcontext fails, the sdmadesc will be freed, but the allocated desc-bd is forgot to be freed. We already met the sdmaloadcontext failure ca...

kernel: rtc: pl031: fix rtc features null pointer dereference

A flaw was found in the rtc-pl031 module in the Linux kernel. The alarm feature bit was cleaned before device initialization, which caused a NULL pointer dereference when there was no interrupt line. This resulted in a system crash and a denial of service...

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...

Kernel: x86/mm: a per-cpu entry area leak was identified through the init_cea_offsets function when prefetchnta and prefetcht2 instructions being used for the per-cpu entry area mapping to the user space

A possible unauthorized memory access flaw was found in the Linux kernel's cpuentryarea mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data.
