CVE-2026-44988

LibVNCClient is a library for easy implementation of a VNC client. In 0.9.15 and earlier, LibVNCClient's Tight encoding decoder uses fixed-size 2048-pixel scratch buffers for the Gradient filter, but it does not reject Tight rectangles whose width is larger than 2048 pixels. A malicious VNC serve...

CVE-2026-46084

In the Linux kernel, the following vulnerability has been resolved: RDMA/manaib: Disable RX steering on RSS QP destroy When an RSS QP is destroyed e.g. DPDK exit, manaibdestroyqprss destroys the RX WQ objects but does not disable vPort RX steering in firmware. This leaves stale steering...

In the Linux kernel, the following vulnerability has been resolved: ipvs: do not keep destdst if dev is going down There is race between the netdev notifier ipvsdstevent and the code that caches dst with dev that is going down. As the FIB can be notified for the closed device after our handler...

UBUNTU-CVE-2026-45987

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Sync interrupt shadow to cached vmcb12 after VMRUN of L2 After VMRUN in guest mode, nestedsynccontrolfromvmcb02 syncs fields written by the CPU from vmcb02 to the cached vmcb12. This is because the cached vmcb12 is use...

CVE-2026-45850

In the Linux kernel, the following vulnerability has been resolved: ipvs: skip ipv6 extension headers for csum checks Protocol checksum validation fails for IPv6 if there are extension headers before the protocol header. iph-len already contains its offset, so use it to fix the problem...

CVE-2025-71305

In the Linux kernel, the following vulnerability has been resolved: drm/display/dpmst: Add protection against 0 vcpi When releasing a timeslot there is a slight chance we may end up with the wrong payload mask due to overflow if the delayeddestroywork ends up coming into play after a DP 2.1 monit...

CVE-2026-23679

libusb before version 1.0.30 contains a NULL pointer dereference vulnerability that allows attackers to crash applications by supplying a malformed USB configuration descriptor where an interface claims bNumEndpoints greater than zero but is followed by a class-specific descriptor whose bLength...

CVE-2026-46063

The CVE-2026-46063 issue affects the Linux kernel with x86 shadow stack (shstk) handling of sigreturn. Root cause: during a shadow-stack sigframe read, the kernel previously held the mmap lock while verifying VMA flags to distinguish shadow stack memory. A page fault during this read could trigge...
