CVE-2023-4272 affects ARM Mali GPU kernel drivers (Midgard, Bifrost, Valhall families) exposing sensitive data from freed memory via local GPU processing operations. Public documents link Mali kernel-driver variants (r8p0–r32p0, r0p0–r41p0, etc.) and describe the vulnerability as local with low a...

kernel: nvme-tcp: don't access released socket during error recovery

A race condition leading to NULL pointer dereference was found in the Linux kernel NVMe-over-TCP driver's error recovery handling. A local user with privileges to execute NVMe management commands can run the 'nvme list' command while NVMe-over-TCP error recovery work is temporarily failing...

kernel: bus: mhi: host: Range check CHDBOFF and ERDBOFF

A missing bounds check flaw was found in the Linux kernel's Modem Host Interface bus driver in the channel doorbell offset validation logic. A local user can trigger this issue on systems with MHI devices typically Qualcomm modems or wireless cards by using a device that provides malformed or...

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: use-after-free in l1oip timer handlers

A use-after-free flaw was found in the Linux kernel’s ISDN over IP tunnel functionality in how a local user triggers the releasecard function called from l1oipcleanup. This flaw allows a local user to crash or potentially escalate their privileges on the system...

kernel: wifi: fix potential NULL-ptr deref after clone

A flaw was found in the Linux kernel’s iwlwifi mei driver. When the driver attempts to clone a socket bufferand that operation fails, it may erroneously dereference a NULL pointer, leading to a kernel crash or denial of service. An unprivileged local user may be able to trigger this flaw by...

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: Type confusion in pick_next_rt_entity()

A memory corruption flaw was found in the Linux kernel's scheduler subsystem. This could allow a local user to crash the system or potentially escalate their privileges on the system...

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 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: 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: 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: 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: 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...
