CVE-2025-40026
CVE-2025-40026 — Linux kernel KVM x86 issue : When completing emulation of an instruction that generated a userspace exit for I/O, the kernel could re-check L1 intercepts even after emulation had completed and the host had effectively allowed L2 to perform the I/O. If the I/O permission bitmaps w...

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...
