QEMU: VNC: NULL pointer dereference in qemu_clipboard_request()

A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemuclipboardrequest function can be reached before vncservercuttextcaps was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a maliciou...

kernel: mptcp: fix UaF in listener shutdown

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix UaF in listener shutdown As reported by Christoph after having refactored the passive socket initialization, the mptcp listener shutdown path is prone to an UaF issue. BUG: KASAN: use-after-free in...

kernel: ipmi_si: fix a memleak in try_smi_init()

A memory leak flaw was found in the Linux kernel's IPMI System Interface driver in the initialization error path. A local user can trigger this issue by loading the ipmisi module when initialization fails after allocating the sism structure but before registering the shutdown handler. This causes...

EDK2: integer overflow in CreateHob() could lead to HOB OOB R/W

A flaw was found in the CreateHob function in EDK2. An attacker, leveraging a local network, can initiate an integer overflow leading to a buffer overflow. This issue arises during size alignment within the CreateHob function, requiring activation in the PEI phase. Successful exploitation of this...

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Handle SRCU initialization failure during page track init Check the return of initsrcustruct, which can fail due to OOM, when initializing the page track mechanism. Lack of checking leads to a NULL pointer deref found b...

CVE-2021-47481

CVE-2021-47481 concerns the Linux kernel RDMA mlx5 path. The connected sources confirm a concrete flaw where the ODP xarray was not initialized when creating an ODP MR, allowing an out-of-bounds/invalid access that triggers a crash (page fault) due to reg_create() setting a desc_size. The fix des...
