CVE-2026-43197

A flaw was found in the Linux kernel's netconsole component. The system processes messages from the console subsystem without ensuring they are properly terminated, which can lead to an out-of-bounds read. This vulnerability allows a local attacker to trigger a kernel crash, resulting in a Denial...

CVE-2026-32603

Sandboxie is an open source sandbox-based isolation software for Windows. In versions 1.17.2 and earlier, a local denial of service vulnerability exists in the Sandboxie kernel driver. An unprivileged process running inside a Standard Sandbox can send a malformed IOCTL to the...

CVE-2026-43159

A flaw was found in the rtl8723bs Wi-Fi driver within the Linux kernel. This vulnerability occurs when a pointer, pwlan, can become null before being used in the rtwfreenetworknolock function, leading to a null pointer dereference. An attacker could potentially exploit this to cause a system cras...

CVE-2026-43136

A flaw was found in the Linux kernel's Human Interface Device HID subsystem, specifically within the logitech-hidpp driver. A remote attacker, by connecting a specially crafted Universal Serial Bus USB device, could send malformed HID report descriptors that lack valid fields. This could lead to ...

CVE-2026-43099

A flaw was found in the Linux kernel, specifically within the IPv4 Internet Protocol version 4 and ICMP Internet Control Message Protocol components. When the IPv6 Internet Protocol version 6 stack is not active, a specific function ipv6devfind can return an error. If this error is then passed to...

CVE-2026-43087

A flaw was found in the Linux kernel's pinctrl subsystem, specifically within the mcp23s08 driver. During system initialization, a hardware chip may have its interrupt-on-change feature enabled on certain pins. This can cause the system to generate interrupts for which no corresponding software...

EUVD-2026-27734

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: xscale: Check for PTP support properly In ixp4xxgettsinfo ixp46xptpfind is called unconditionally despite this feature only existing on ixp46x, leading to the following splat from tcpdump: root@OpenWrt: tcpdump -vv...

CVE-2026-43175

The CVE-2026-43175 issue affects the Linux kernel’s clk: rs9 component, where the 9FGV0841 driver registers 8 clk_hw instances but the code did not guarantee 8 slots, risking an out-of-bounds write to rs9_driver_data.clk_dif[4..7] and corruption of adjacent data. All connected sources consistentl...

CVE-2026-43169

In the Linux kernel, the following vulnerability has been resolved: drm/buddy: Prevent BUGON by validating rounded allocation When DRMBUDDYCONTIGUOUSALLOCATION is set, the requested size is rounded up to the next power-of-two via rounduppowoftwo. Similarly, for non-contiguous allocations with lar...

CVE-2026-43087

The CVE-2026-43087 issue affects the Linux kernel’s pinctrl/mcp23s08 driver. Root cause: during probe, reg_defaults were removed from the regmap, causing the MCP_GPINTEN value to be read from the chip (possibly non-zero) and trigger a nested IRQ handler that may not exist, leading to a kernel cra...
