CVE-2025-40026 KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Don't recheck L1 intercepts when completing userspace I/O When completing emulation of instruction that generated a userspace exit for I/O, don't recheck L1 intercepts as KVM has already finished that phase of instructi...

CVE-2025-40026

The CVE-2025-40026 entry concerns the Linux kernel KVM on x86. The issue arises when completing userspace I/O emulation: KVM should not recheck L1 intercepts because it has already completed that phase, but if the I/O permission bitmaps are modified during the exit to userspace, KVM may treat the...

PT-2025-44093

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.16.0-rc5-c1610d2d66b1-next-vm Description The Linux kernel contains an issue within the KVM component related to handling L1 intercepts during userspace I/O completion. Specifically, the kernel may recheck L1...

kernel: wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values

A vulnerability was found in the cfg80211 component in the Linux kernel, where a lack of proper range validation applied to the NL80211ATTRTXQQUANTUM can lead to a scenario where the userspace passes an extremely high value that the kernel is not designed to handle efficiently ex. 2^31. This can...
