Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A denial of service attack vulnerability exists in the Linux Kernel. The vulnerability is due to a memory leak found in ctnetlinkcreateconntrack in...

mariadb: assertion failure at table->get_ref_count() == 0 in dict0dict.cc

MariaDB v10.5 to v10.7 was discovered to contain an assertion failure at table-getrefcount == 0 in dict0dict.cc...

kernel: media: dvbdev: adopts refcnt to avoid UAF

In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: adopts refcnt to avoid UAF dvbunregisterdevice is known that prone to use-after-free. That is, the cleanup from dvbunregisterdevice releases the dvbdevice even if there are pointers stored in file-privatedata still...

kernel: EDAC/i10nm: fix refcount leak in pci_get_dev_wrapper()

In the Linux kernel, the following vulnerability has been resolved: EDAC/i10nm: fix refcount leak in pcigetdevwrapper As the comment of pcigetdomainbusandslot says, it returns a PCI device with refcount incremented, so it doesn't need to call an extra pcidevget in pcigetdevwrapper, and the PCI...

Ubuntu 22.04 LTS / 23.10 : Linux kernel vulnerabilities (USN-6503-1)

The remote Ubuntu 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6503-1 advisory. Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local...

kernel: Linux kernel: Resource exhaustion in amdgpu due to PCI device reference count leak

A flaw was found in the Linux kernel's drm/amdgpu component. A missing call to pcidevput in the amdgpuatrmgetbios function leads to a PCI device reference count leak. A local attacker could exploit this to cause resource exhaustion, potentially resulting in a Denial of Service DoS...

kernel: Linux kernel: Denial of Service due to PCI device reference count leak

A flaw was found in the Linux kernel. A local low-privileged user could exploit a reference count leak in the drm/amdgpu component. This vulnerability, related to how PCI Peripheral Component Interconnect devices are managed, could lead to a Denial of Service DoS by exhausting system resources...

kernel: perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix reference count leak in hswephaslimitsbox pcigetdevice will increase the reference count for the returned 'dev'. We need to call pcidevput to decrease the reference count. Since 'dev' is only used in...

kernel: net/sunrpc: fix potential memory leaks in rpc_sysfs_xprt_state_change()

A flaw was found in the sunrpc module in the Linux kernel. A missing decrement of the reference count when an error occurs can cause a memory leak, and a missing check can cause a NULL pointer dereference, potentially resulting in a denial of service...

kernel: soundwire: bus: Fix unbalanced pm_runtime_put() causing usage count underflow

A reference count underflow flaw was found in the Linux kernel's SoundWire bus driver. When pmruntimeresumeandget returns an error -EACCES, the code continues execution and calls pmruntimeput at the end, even though the usage count was never incremented. This causes a usage count underflow in the...

kernel: cifs: Fix memory leak when using fscache

A flaw was found in the cifs module in the Linux kernel. A missing decrement of the reference count will cause a memory leak, potentially impacting system performance and resulting in a denial of service...

kernel: regulator: scmi: Fix refcount leak in scmi_regulator_probe

In the Linux kernel, the following vulnerability has been resolved: regulator: scmi: Fix refcount leak in scmiregulatorprobe offindnodebyname returns a node pointer with refcount incremented, we should use ofnodeput on it when done. Add missing ofnodeput to avoid refcount leak...

kernel: iommu/amd: Fix pci device refcount leak in ppr_notifier()

A reference counting violation was found in the Linux kernel's AMD IOMMU PPR Peripheral Page Request notification handler. When the handler looks up PCI devices using pcigetdomainbusandslot, it receives a reference-counted device pointer but never releases that reference before returning. This...

kernel: perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix reference count leak in hswephaslimitsbox pcigetdevice will increase the reference count for the returned 'dev'. We need to call pcidevput to decrease the reference count. Since 'dev' is only used in...

kernel: irqchip/gic-v3: Fix error handling in gic_populate_ppi_partitions

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3: Fix error handling in gicpopulateppipartitions ofgetchildbyname returns a node pointer with refcount incremented, we should use ofnodeput on it when not need anymore. When kcalloc fails, it missing ofnodeput and...

kernel: usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe()

A reference count leak was found in the wusb3801 USB Type-C driver. When wusb3801hwinit fails during probe, the firmware node reference is not properly released, causing a gradual memory leak...

kernel: iommufd: IOMMUFD_DESTROY should not increase the refcount

A race condition was identified in the iommufd subsystem of the Linux kernel where the IOMMUFDDESTROY command incorrectly increments an object’s reference count without holding the expected exclusive synchronization destroyrwsem. This violates the assumption that temporary reference count...

kernel: bpf, sockmap: Fix repeated calls to sock_put() when msg has more_data

A reference-count flaw was found in the Linux kernel Berkeley Packet Filter BPF sockmap implementation. When processing messages with remaining data, the same Transmission Control Protocol TCP socket reference could be released more than once. A local user running BPF sockmap programs could use...
