Linux kernel buffer overflow vulnerability (CNVD-2023-48543)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel suffers from a buffer overflow vulnerability that originates from an out-of-bounds memory access flaw in the XFS file system, which can be exploited by an attacker...

The vulnerability of the io_sqe_buffer_register() function in the io_uring/rsrc.c module of the Linux operating system allows a hacker to increase their privileges within the system or gain access to protected information.

The vulnerability of the iosqebufferregister function in the iouring/rsrc.c module of the Linux kernel is related to the out-of-bound access to allocated memory. Exploiting this vulnerability can allow an attacker to enhance their privileges within the system or gain access to protected informati...

kernel: RDMA/hfi1: Prevent panic when SDMA is disabled

A possible NULL pointer dereference was observed in the Linux kernel in hfil module. This may lead to kernel panic and then crash...

kernel: RDMA/rxe: Fix mr->map double free

A double-free vulnerability was found in the Linux kernel RDMA RXE soft-RoCE driver's memory region handling. A local user with access to RDMA userspace verbs can register a memory region with parameters that cause initialization to fail, triggering error handling code that frees the mr-map...

kernel: RDMA/rxe: Fix error unwind in rxe_create_qp()

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix error unwind in rxecreateqp In the function rxecreateqp, rxeqpfrominit is called to initialize qp, internally things like the spin locks are not setup until rxeqpinitreq. If an error occures before this point then t...

kernel: RDMA/srpt: Fix a use-after-free

In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Fix a use-after-free Change the LIO port members inside struct srptport from regular members into pointers. Allocate the LIO port data structures from inside srptmaketport and free these from inside srptmaketport. Keep...

kernel: RDMA/rxe: Fix BUG: KASAN: null-ptr-deref in rxe_qp_do_cleanup

A flaw was found in the rdmarxe module in the Linux kernel. A NULL pointer dereference can be triggered when an error occurs due to an improper check, resulting in a denial of service...

kernel: RDMA/rxe: Fix "kernel NULL pointer dereference" error

A NULL pointer dereference vulnerability was found in the RXE Soft-RoCE RDMA driver in the Linux kernel. When rxequeueinit fails during queue pair initialization in rxeqpinitreq, the task function and argument pointers qp-req.task.func and qp-req.task.arg remain uninitialized. The cleanup functio...

kernel: RDMA/siw: Fix duplicated reported IW_CM_EVENT_CONNECT_REPLY event

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fix duplicated reported IWCMEVENTCONNECTREPLY event If siwrecvmparr returns -EAGAIN, it means that the MPA reply hasn't been received completely, and should not report IWCMEVENTCONNECTREPLY in this case. This may trigge...

kernel: udmabuf: Set the DMA mask for the udmabuf device (v2)

In the Linux kernel, the following vulnerability has been resolved: udmabuf: Set the DMA mask for the udmabuf device v2 If the DMA mask is not set explicitly, the following warning occurs when the userspace tries to access the dma-buf via the CPU as reported by syzbot here: WARNING: CPU: 1 PID:...

CVE-2023-2124

CVE-2023-2124 is an out-of-bounds memory access flaw in the Linux kernel XFS image restore path after failure with a dirty log journal. It can crash a local user or potentially escalate privileges when mounting/correcting a corrupted XFS disk image. Public advisories (e.g., Debian DSA-5448-1 and ...

The vulnerability of the Linux operating system’s kernel InfiniBand driver allows a hacker to trigger a service failure or increase their privileges.

The vulnerability in the Linux operating system’s kernel InfiniBand driver is related to the improper preparation of parameters for the rdmabindaddr function. This leads to reading beyond the allocated memory boundary in the comparenetdevandip function within the drivers/infiniband/core/cma.c...
