CVE-2026-80643

This Linux kernel issue affects the igen6_edac driver (EDAC subsystem for Igen6 memory controllers). When the driver is unloaded, a kernel warning and call trace are triggered because the memory controller devices lack a required release() callback, as reported by the kobject core in drivers/base...

CVE-2026-80643 EDAC/igen6: Fix call trace due to missing release()

In the Linux kernel, the following vulnerability has been resolved: EDAC/igen6: Fix call trace due to missing release When unloading the igen6edac driver, there is a call trace: Device 'null' does not have a release function, it is broken and must be fixed. See Documentation/core-api/kobject.rst...

In the Linux kernel, the following vulnerability has been resolved: wifi: wlcore: enable the right set of ciphers The firmware version number check for IGTK introduced in commit c34dbc5900b0 "wifi: wlcore: Add support for IGTK key" lets the amount of ciphers decrease on every boot of a too old...

CVE-2026-80642

CVE-2026-80642 affects the Linux kernel 's liveupdate subsystem. During a Live Update, a subsystem may need to hold incoming File-Lifecycle-Bound (FLB) data for an extended period (e.g., during device enumeration). The vulnerability stems from a missing reference count on the incoming FLB structu...

CVE-2026-80641

CVE-2026-80641 affects the Linux kernel wlcore WiFi driver (TI wl12xx and wl18xx chips). The root cause is a firmware version check for IGTK (Individual Group Traffic Key) introduced in an earlier commit that causes the number of enabled ciphers to decrement on every boot when running too-old fir...

CVE-2026-80642 liveupdate: Reference count incoming FLB data

In the Linux kernel, the following vulnerability has been resolved: liveupdate: Reference count incoming FLB data Increment the incoming FLB refcount in liveupdateflbgetincoming so that the FLB structure cannot be freed while the caller is actively using it. Add an additional...

CVE-2026-80640

CVE-2026-80640 affects the CXL firmware control (fwctl) subsystem of the Linux kernel . The root cause is in cxlctl_get_supported_features(), where num_entries is not initialized early enough, causing the kernel's Fortify runtime protection to detect a potential 48-byte write to a zero-size buffe...
