CVE-2024-50296

CVE-2024-50296 affects the Linux kernel net/hns3 driver (and related SR-IOV cleanup path). Root cause: race in driver removal where concurrent VF disable and resource release call pci_disable_sriov() twice, leading to a NULL pointer dereference during device removal. Impact: kernel crash when the...

CVE-2024-50296 net: hns3: fix kernel crash when uninstalling driver

In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix kernel crash when uninstalling driver When the driver is uninstalled and the VF is disabled concurrently, a kernel crash occurs. The reason is that the two actions call function pcidisablesriov. The numVFs is check...

kernel: mmc: atmel-mci: fix return value check of mmc_add_host()

In the Linux kernel, the following vulnerability has been resolved: mmc: atmel-mci: fix return value check of mmcaddhost mmcaddhost may return error, if we ignore its return value, it will lead two issues: 1. The memory that allocated in mmcallochost is leaked. 2. In the remove path, mmcremovehos...

kernel: thermal: of: fix double-free on unregistration

A flaw was found in the Linux kernel's thermal subsystem. A double-free vulnerability occurs during thermal zone device unregistration when using device tree OF bindings. The thermalofzoneregister function leaks the original tzp structure and double-frees the internal copy, which can lead to memo...

kernel: block: fix request.queuelist usage in flush

A vulnerability was found in the Linux kernel's block subsystem, where the issue arises when the request queue list is not properly initialized for the first request in the PREFLUSH/POSTFLUSH sequences, leading to potential kernel crashes due to improper list manipulation...

kernel: Kernel: Denial of Service via improper return value check in mmc_add_host()

A flaw was found in the Linux kernel's mmc: wmt-sdmmc component. An improper return value check in the mmcaddhost function may allow a local attacker to cause a memory leak. This can lead to a kernel crash, resulting in a Denial of Service DoS...

kernel: Kernel: Denial of Service in mmc: moxart due to improper return value check

A flaw was found in the Linux kernel component mmc: moxart. A local attacker with low privileges could exploit this vulnerability by triggering an improper return value check in the mmcaddhost function. This oversight can lead to a memory leak, which may ultimately cause a kernel crash, resulting...

kernel: RDMA/srpt: Support specifying the srpt_service_guid parameter

A flaw was foundin the Linux Kernel when specifying the srptserviceguid parameter, which may lead to kernel crash...

kernel: nfs: pass explicit offset/count to trace events

nfs in linux kernel permits using nfsfoliolength without locking the folio and without checking for null mapping. This can permit truncation and lead to kernel crash...

kernel: vmxnet3: disable rx data ring on dma allocation failure

A vulnerability was found in the Linux kernel's vmxnet3 driver in the vmxnet3rqcreate function, where this issue occurs when memory allocation fails for the RX data ring, leading to an improper reference size that may cause the hypervisor to access invalid memory during packet reception, which ca...

kernel: mm: vmalloc: check if a hash-index is in cpu_possible_mask

A vulnerability was found in the Linux kernel that involves improper handling of per-CPU data in systems where cpupossiblemask has gaps between CPUs. This can lead to an index which accesses non-existent or unset CPU areas and potentially causes kernel crashes...

kernel: can: dev: can_put_echo_skb(): don't crash kernel if can_priv::echo_skb is accessed out of bounds

In the Linux kernel, the following vulnerability has been resolved: can: dev: canputechoskb: don't crash kernel if canpriv::echoskb is accessed out of bounds If the "struct canpriv::echooskb" is accessed out of bounds, this would cause a kernel crash. Instead, issue a meaningful warning message a...

kernel: net: hns3: fix kernel crash problem in concurrent scenario

In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix kernel crash problem in concurrent scenario When link status change, the nic driver need to notify the roce driver to handle this event, but at this time, the roce driver may uninit, then cause kernel crash. To fix...
