In the Linux kernel, the following vulnerability has been resolved: perf/amd/ibs: Avoid calling perfallowkernel from the IBS NMI handler Calling perfallowkernel from the NMI context is unsafe and could be fatal. Capture the permission at event-initialization time by storing it in event-hw.flags,...

PT-2026-51953

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An integer overflow exists in the device-mapper log dm log component. The region count local variable in the create log context function is declared as a 32-bit unsigned integer, while t...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...

EUVD-2026-37804

In SignalRGB versions prior to 1.3.7.0, seven of the thirteen IOCTL handlers dereference the SystemBuffer pointer without first verifying that it is non-NULL. Sending an IOCTL with an empty input buffer causes a NULL pointer dereference, resulting in a kernel crash...

Siemens RUGGEDCOM RST2428P Improper Input Validation (CVE-2025-40254)

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: remove never-working support for setting nsh fields The validation of the setnsh... action is completely wrong. It runs through the nshkeyputfromnlattr function that is the same function that validates NSH keys...

Siemens RUGGEDCOM RST2428P Improper Input Validation (CVE-2026-23238)

"In the Linux kernel, the following vulnerability has been resolved: romfs: check sbsetblocksize return value romfsfillsuper ignores the return value of sbsetblocksize, which can fail if the requested block size is incompatible with the block device's configuration. This can be triggered by setti...

CVE-2026-8050

The SignalRGB kernel driver, SignalIo.sys (or SignalRgbDriver.sys), is vulnerable to a NULL pointer dereference in versions prior to 1.3.7.0 . Specifically, seven of the sixteen IOCTL handlers fail to verify that the SystemBuffer pointer is non-NULL before dereferencing it. An authenticated local...
