Microsoft has listed CVE-2026-45644 as an elevation-of-privilege vulnerability in the Microsoft Live Share Canvas SDK in its June 2026 Security Update Guide, making this a developer-supply-chain security issue rather than a conventional Windows desktop patch emergency. The important word is not...

Microsoft disclosed CVE-2026-45482 on June 9, 2026, as an Important-rated security feature bypass in the Microsoft Visual Studio Code Copilot Chat extension, caused by a path traversal weakness that can let a local unauthorized attacker bypass an authentication-related security feature. The...

Microsoft’s CVE-2026-45474 advisory describes a Microsoft Office remote code execution vulnerability because the attacker can be remote from the victim, even though the CVSS attack vector is local because exploitation requires malicious code or content to run on the target machine during the...

Linux kernel maintainers published CVE-2026-46157 on May 28, 2026, after fixing a race in the ALSA PCM OSS compatibility layer where concurrent access to runtime.oss.trigger could corrupt adjacent bit fields and destabilize audio handling. The bug is not a glamorous remote-code-execution...

CVE-2026-46197 is a newly published Linux kernel vulnerability, received by NVD on May 28, 2026, in AMD’s amdkfd GPU compute driver, where an unchecked user-controlled SVM attribute count could allow out-of-bounds buffer access before the kernel-side ioctl handler validates the request. The fix...

CVE-2026-46031 is a Linux kernel networking flaw published by NVD on May 27, 2026, affecting the Micrel/Kendin KS8851 Ethernet driver, where interrupt handling can re-enter transmit processing and deadlock the kernel under specific timing and configuration conditions. It is not the kind of...

CVE-2026-46006 is a newly published Linux kernel vulnerability, disclosed by NVD on May 27, 2026, affecting Nouveau’s DRM graphics driver where a 32-bit integer overflow could undermine a relocation bounds check in push buffer handling. The bug is small enough to fit in a one-line patch, but it...

CVE-2026-46069 is a Linux kernel Wi-Fi driver vulnerability, published by NVD on May 27, 2026, in the Marvell mwifiex adapter cleanup path, where a wakeup timer callback can keep running after driver teardown and touch memory that may already have been freed. The bug is small in code but large...

CVE-2026-45997 is a Linux kernel storage-driver vulnerability published by NVD on May 27, 2026, after kernel.org assigned a CVE to a fixed SCSI disk error path that failed to release a gendisk reference when device registration failed. The bug is not the kind of headline-grabbing...

CVE-2026-46037 is a newly published Linux kernel flaw disclosed by kernel.org and NVD on May 27, 2026, affecting IPv4 ICMP handling where extended echo replies could drive an out-of-range lookup in the kernel’s icmp_pointers table before validation. The bug is small in code and large in...

CVE-2026-43414 is a Linux kernel vulnerability published on May 8, 2026, affecting the qla2xxx SCSI Fibre Channel driver, where faulty error handling can free the same fcport object twice and kernel.org assigned it a CVSS 3.1 score of 9.8, Critical. The oddity is not that an obscure storage...

Microsoft has published CVE-2026-26164 as a Microsoft 365 Copilot information disclosure vulnerability in its Security Update Guide, identifying it as a cloud-era security issue where Copilot could expose information over a network rather than a traditional Windows patching problem. The...

CVE-2026-43213 is a Linux kernel flaw disclosed by kernel.org and listed by Microsoft’s Security Update Guide on May 6, 2026, affecting the Realtek rtw89 PCI Wi-Fi driver when malformed TX release report sequence numbers trigger an out-of-bounds access and kernel crash. The bug is not the sort...

CVE-2026-43172 is a newly published Linux kernel vulnerability disclosed on May 6, 2026, affecting Intel’s iwlwifi driver, where malformed firmware reporting for 22000-series wireless hardware could trigger an out-of-bounds array access during shared-memory parsing. The bug is narrow, technical...

CVE-2026-7338 is a high-severity use-after-free flaw in Chromium’s Cast component, disclosed on April 28, 2026, and fixed in Google Chrome 147.0.7727.138 after researchers found local-network malicious traffic could potentially trigger heap corruption before the update. The vulnerability is not...

Linux kernel maintainers have published a fix for CVE-2026-31619, a flaw in the ALSA fireworks FireWire audio driver that can let a device-supplied 32-bit status value run past the end of a string table. The bug is narrowly scoped, but it is exactly the kind of kernel defect that matters: a...

In the Linux kernel’s Bluetooth stack, CVE-2026-31498 is the kind of bug that looks routine at first glance and then turns out to be two problems in one: a resource leak in L2CAP ERTM reconfiguration and a potential infinite loop triggered by a zero packet size. The published fix targets the...

Linux administrators received a fresh reminder this week that ext4’s maturity does not make it immune to memory-safety bugs. CVE-2026-31449 is a slab-out-of-bounds read in the Linux kernel’s ext4 extent-tree logic, and it appears in a code path that corrects index entries after leaf extents are...

Linux has published CVE-2026-31510 for a Bluetooth L2CAP bug that can crash the kernel when l2cap_sock_ready_cb touches a sk pointer without first checking whether it is NULL. The published record includes a KASAN-backed null-pointer dereference trace and ties the issue to an l2cap_info_timeout...

CVE-2026-31489 is a classic Linux kernel lifetime bug with outsized operational meaning: a seemingly small double-put in the Meson SPI controller driver can still turn into a crash, a teardown failure, or a hard-to-debug stability problem when a system removes the device. The issue is simple on...
