CVE-2026-47760

CVE-2026-47760 affects TinyMCE before 7.1.0, where an XSS flaw arises from improper SVG namespace scope handling in the sanitizer. The issue allows a crafted payload using nested SVG elements to bypass attribute sanitization and execute arbitrary JavaScript. Affected versions are 6.8.0 up to, but...

CVE-2026-47760 TinyMCE Cross-Site Scripting (XSS) vulnerability using sanitization bypass through nested SVGs

TinyMCE is an open source rich text editor. From 6.8.0 to before 7.1.0, TinyMCE contains an XSS vulnerability caused by improper SVG namespace scope handling in the sanitizer. A crafted payload using nested elements can bypass attribute sanitization and execute arbitrary JavaScript. This...

kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...

CVE-2026-46131

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: check for nEPT/nNPT in slow flush hypercalls Checking isguestmodevcpu is incorrect, because translatenestedgpa is only valid if an L2 guest is running with nested EPT/NPT enabled. Instead use the same condition as...

CVE-2026-46131

The CVE-2026-46131 entry concerns the Linux kernel KVM/x86 hypervisor path. It states a vulnerability in the slow flush hypercalls where the is_guest_mode(vcpu) check is incorrect; translate_nested_gpa() is only valid if an L2 guest is running with nested EPT/NPT enabled. The fix uses the same co...

SUSE 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...

SUSE CVE-2026-46032

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Triple fault if restore host CR3 fails on nested VMEXIT If loading L1's CR3 fails on a nested VMEXIT, nestedsvmvmexit returns an error code that is ignored by most callers, and continues to run L1 with corrupted state....

SUSE CVE-2026-46059

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Always use NextRIP as vmcb02's NextRIP after first L2 VMRUN For guests with NRIPS disabled, L1 does not provide NextRIP when running an L2 with an injected soft interrupt, instead it advances the current RIP before...
