UBUNTU-CVE-2023-53840

In the Linux kernel, the following vulnerability has been resolved: usb: early: xhci-dbc: Fix a potential out-of-bound memory access If xdbcbulkwrite fails, the values in 'buf' can be anything. So the string is not guaranteed to be NULL terminated when xdbctrace is called. Reserve an extra byte,...

UBUNTU-CVE-2023-53861

In the Linux kernel, the following vulnerability has been resolved: ext4: correct grp validation in ext4mbgoodgroup Group corruption check will access memory of grp and will trigger kernel crash if grp is NULL. So do NULL check before corruption check...

kernel: cifs: fix oops during encryption

An out-of-bounds memory access vulnerability exists in the linux kernel, such that A stack-allocated buffer backed by vmalloc was passed into crypto code scatterwalkmapandcopy → memcpy where a cross-page write occurred. This ended up hitting a read-only mapping, causing a page-level fault and...

CVE-2025-40330

In the Linux kernel, the following vulnerability has been resolved: bnxten: Shutdown FW DMA in bnxtshutdown The netifclose call in bnxtshutdown only stops packet DMA. There may be FW DMA for trace logging recently added that will continue. If we kexec to a new kernel, the DMA will corrupt memory ...

CVE-2025-40330

CVE-2025-40330 affects the bnxt_en driver in the Linux kernel. The vulnerability arose because bnxt_shutdown()’s netif_close() only halts packet DMA, potentially leaving firmware DMA (such as trace logging) active. If the system kexeces to a new kernel, this DMA could corrupt memory in the new ke...

CVE-2023-53840

The CVE-2023-53840 issue in the Linux kernel is fixed in the usb: early: xhci-dbc path. If xdbc_bulk_write() fails, the contents of buf could be non-deterministic and not NULL-terminated when xdbc_trace() runs, risking a potential out-of-bounds read. The patch reserves an extra byte in the static...

CVE-2022-50671

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix "kernel NULL pointer dereference" error When rxequeueinit in the function rxeqpinitreq fails, both qp-req.task.func and qp-req.task.arg are not initialized. Because of creation of qp fails, the function rxecreateqp...

CVE-2022-50666

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fix QP destroy to wait for all references dropped. Delay QP destroy completion until all siw references to QP are dropped. The calling RDMA core will free QP structure after successful return from siwqpdestroy call, so...

DEBIAN-CVE-2022-50647

In the Linux kernel, the following vulnerability has been resolved: RISC-V: Make port I/O string accessors actually work Fix port I/O string accessors such as insb', outsb', etc. which use the physical PCI port I/O address rather than the corresponding memory mapping to get at the requested...

UBUNTU-CVE-2023-53801

In the Linux kernel, the following vulnerability has been resolved: iommu/sprd: Release dma buffer to avoid memory leak When attaching to a domain, the driver would alloc a DMA buffer which is used to store address mapping table, and it need to be released when the IOMMU domain is freed...

CVE-2023-53811 RDMA/irdma: Cap MSIX used to online CPUs + 1

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Cap MSIX used to online CPUs + 1 The irdma driver can use a maximum number of msix vectors equal to numonlinecpus + 1 and the kernel warning stack below is shown if that number is exceeded. The kernel throws a warning...

CVE-2023-53778

In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Clean up integer overflow checking in mapuserpages The encodedma function has some validation on intrans-size but it would be more clear to move those checks to findandmapuserpages. The encodedma had two checks: if...
