CVE-2026-43156

The CVE-2026-43156 entry affects the Linux kernel USB Pegasus driver. The root cause is that pegasus_probe() built URBs using hardcoded endpoint pipes (RX bulk 1, TX bulk 2, status interrupt 3) without validating endpoint descriptors, allowing a malformed USB device to present endpoints with mism...

VM2 Sandbox Breakout Through __lookupGetter__

Summary VM2 suffers from a sandbox breakout vulnerability. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. Details The lookupGetter method allows to read the getter of an object. It is special in VM2 since it will switch...

RHCOS 4 : Red Hat build of MicroShift 4.16.24 (RHSA-2024:10149)

The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2024:10149 advisory. - runc: file descriptor leak CVE-2024-21626 Note that Nessus has not tested for this issue but has instead relied only on the application's...

curl: Potential Resource Leak in tool_parsecfg.c at line 279 during fileerror

Summary: A resource leak was identified in src/toolparsecfg.c using the Clang Static Analyzer. When a file error occurs fileerror is true during config parsing, the function returns PARAMREADERROR without ensuring the file stream is properly closed, leading to a potential file descriptor leak...

CVE-2026-31709

In the Linux kernel, the following vulnerability has been resolved: smb: client: validate the whole DACL before rewriting it in cifsacl buildsecdesc and idmodetocifsacl derive a DACL pointer from a server-supplied dacloffset and then use the incoming ACL to rebuild the chmod/chown security...

CVE-2026-43031

The CVE concerns the Linux kernel xilinx axienet driver. When a TX packet spans multiple buffer descriptors, the current accounting in axienet_free_tx_chain summing per-BD lengths into an accumulator can lose earlier bytes if the packet completes across different polls, causing BQL to overestimat...

CVE-2026-31769

The CVE-2026-31769 issue in the Linux kernel gpib module is resolved by adding a kernel-only descriptor_busy reference count in struct gpib_descriptor to prevent use-after-free of gpib_descriptor objects during concurrent IO ioctl handling (IBRD, IBWRT, IBCMD, IBWAIT). Each IO path increments des...
