kernel: Linux kernel UDPLITE: Denial of Service via null pointer dereference

A flaw was found in the Linux kernel's UDPLITE UDP-Lite implementation. A local user can exploit a null pointer dereference in the skmemraiseallocated function by using the IPPROTOUDPLITE protocol. This vulnerability can lead to a system crash, resulting in a denial of service DoS...

kernel: x86/mm: Randomize per-cpu entry area

A possible unauthorized memory access flaw was found in the Linux kernel cpuentryarea mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data. This issue could allow a local user to gain access to some important data with expected locatio...

kernel: net/tls: tls_is_tx_ready() checked list_entry

A memory leak flaw was found in the Linux kernel's TLS protocol. This issue could allow a local user unauthorized access to some memory...

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: Linux kernel: Denial of Service via deadlock in net/smc

A flaw was found in the Linux kernel's Server Message Block SMB over Remote Direct Memory Access RDMA net/smc module. This vulnerability allows a local user to trigger a deadlock within the system. The deadlock occurs due to a circular locking dependency when specific operations involving...

kernel: Linux kernel: Resource leak in regulator_register can cause system unavailability

A flaw was found in the Linux kernel. This vulnerability, a resource leak within the regulatorregister function, can be exploited by a local user. Successful exploitation could lead to a Denial of Service DoS, making the system unavailable due to resource exhaustion...

kernel: net/sched: sch_fq: fix integer overflow of "credit"

An integer overflow flaw was found in the Linux kernel network fair-queueing scheduler in the way the initial per-flow credit is set. If a configuration provides an excessively large initial quantum, the credit value can overflow to a negative number, leading to excessive scheduling and soft...

kernel: cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver

A reference leak flaw was found in the Linux kernel's AMD P-state unit test driver in the CPU policy access logic. A local user can trigger this issue by loading the amd-pstate-ut driver, which acquires CPU policy references via cpufreqcpuget without releasing them via cpufreqcpuput. This causes...

kernel: kernel: Denial of Service due to xid leak in cifs_flock()

A flaw was found in the Linux kernel. This vulnerability, a resource leak, occurs in the CIFS Common Internet File System component within the cifsflock function. A local user could exploit this by not using flock, which prevents the transaction identifier xid from being freed, leading to a...

kernel: Linux kernel CXL driver: Use-after-free vulnerability leading to system instability or privilege escalation

A flaw was found in the Linux kernel's CXL driver. This vulnerability, a use-after-free, allows a local user to cause system instability or a denial of service. The issue arises when the cxlparsecfmws function attempts to use memory that has already been released. This could potentially lead to...

kernel: drm/i915/gvt: fix vgpu debugfs clean in remove

A NULL pointer dereference was found in the Linux kernel Intel i915 graphics driver's virtual GPU debugfs cleanup handling. A local user with privileges to unbind the i915 driver can trigger driver removal on systems with active virtual GPU instances, causing the cleanup path to attempt removing...

kernel: RDMA/core: Make sure "ib_port" is valid when access sysfs node

A NULL pointer dereference flaw was found in the Linux kernel RDMA core's sysfs handling. A local user with access to InfiniBand sysfs nodes can read sysfs attributes while an InfiniBand port is being removed, causing the kernel to dereference a NULL ibport pointer when the port structure has bee...

kernel: mpls: double free on sysctl allocation failure

A double-free flaw was found in the Linux kernel when the MPLS implementation handled sysctl allocation failures. This issue could allow a local user to cause a denial of service or possibly execute arbitrary code...

kernel: tap: tap_open(): correctly initialize socket uid

A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and get unauthorized access to some resources...

kernel: tap: tap_open(): correctly initialize socket uid next fix of i_uid to current_fsuid

A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -...

kernel: Linux kernel xHCI DbC: Denial of Service via memory leak

A flaw was found in the Linux kernel's xHCI Debug Capability DbC module. A local user with low privileges could exploit a memory leak in the xhciallocdbc function. This occurs when the DbC is already in use, and allocated memory for the xhcidbc structure is not properly released. This vulnerabili...

kernel: drm/virtio: Check whether transferred 2D BO is shmem
