UBUNTU-CVE-2026-98715

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Preserve TLB control i.e. pending TLB flush on failed VMRUN Don't reset the VMCB's TLB control back to "do nothing" on a failed VMRUN, as empirical testing shows that the CPU performs the requested TLB flush if and only...

UBUNTU-CVE-2026-98716

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Use the active VMCB's MSR bitmap when checking if MSR is intercepted Use the MSR permission bitmap of the active VMCB instead of assuming that KVM is always using vmcb02's bitmap when L2 is active, as KVM uses msrpm02 i...

UBUNTU-CVE-2026-98724

In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: reject too-short SGL segments The host controls an SGL segment's length. A nonzero length smaller than one SGL descriptor makes nrdescs zero, so nvmetpciepfgetsglsegment reads the type byte of sgls-1 outside the...

UBUNTU-CVE-2026-98708

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: keep paired old chanctx alive An in-place replacement keeps reciprocal replacectx pointers between the old WILLBEREPLACED chanctx and the new REPLACESOTHER chanctx. However, the early free paths only consider...

UBUNTU-CVE-2026-98773

In the Linux kernel, the following vulnerability has been resolved: USB: cdc-acm: skip URB restart in portshutdown if disconnected acmportshutdown is called from the tty-port machinery whenever the last user closes the port. acmdisconnect sets acm-disconnected and calls ttyportttyvhangup, which...

UBUNTU-CVE-2026-98772

In the Linux kernel, the following vulnerability has been resolved: USB: serial: fix port tear down use-after-free Some drivers for multiport devices access port driver data from completion handlers of shared URBs submitted at attach or first open and stopped at disconnect or last close,...

UBUNTU-CVE-2026-98771

In the Linux kernel, the following vulnerability has been resolved: usb: storage: sierrams: reject short SWoC info transfers sierragetswocinfo requests sizeofstruct swocinfo 60 bytes from the device via usbcontrolmsg, but its callers only treat a negative return value as failure. A device that...

UBUNTU-CVE-2026-98694

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Fix KASAN reported use-after-free when request is canceled Alan reported that when doing stress testing sometimes KASAN notices use-after-free during control channel operation stripped down keeping the relevant parts...

UBUNTU-CVE-2026-98699

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix mesh fast xmit path deletion UAF meshfasttxcache stores raw meshpath pointers. Path deletion flushes the cache and then frees the path with kfreercu, but a lookup that already holds the path can insert a new...

UBUNTU-CVE-2026-98687

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Reject oversized XDomain properties responses tbxdppropertiesrequest allocates room for 45 data dwords in its 252-byte response buffer. The XDomain length field is six bits wide, however, and a malicious peer can set...

UBUNTU-CVE-2026-98691

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Tear down inactive DP tunnels when the domain is stopped tbstop only tears down DMA tunnels so a DP tunnel that is still waiting for dprxwork to complete keeps that work queued while the routers are removed and the...

UBUNTU-CVE-2026-98689

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Don't access a DP tunnel after its DPRX read was canceled tbdpdprxwork checks -dprxcanceled before it takes tb-lock so it misses a tbdpdprxstop that could not cancel the already running work. It then polls the DPRX...

UBUNTU-CVE-2026-98688

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Fix NULL dereference in tbremovework There is a slight race between tbremovework and tbdomainremove which leads to dereferencing a NULL tb-rootswitch pointer inside tbfreeunpluggedxdomains: Thread A Thread B...

UBUNTU-CVE-2026-98693

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Hold a router reference for each allocated HopID tbstop drops the reference to all DP tunnels but does not deactivate them, thus nothing cancels a dprxwork still in flight which holds its own tunnel reference and the...

UBUNTU-CVE-2026-98662

In the Linux kernel, the following vulnerability has been resolved: iio: light: gp2ap020a00f: drain irqwork after freeirq The threaded IRQ handler queues data-work through irqworkqueue so the trigger is polled from a per-CPU context. freeirq does not flush an irqwork the handler already queued, s...

UBUNTU-CVE-2026-98661

In the Linux kernel, the following vulnerability has been resolved: iio: light: rohm-bu27034: Fix infinite delay on error When reading an integration-time fails, the code will use error code to compute the sleep time. Fix this by using the smallest integration time as a default if reading fails...

UBUNTU-CVE-2026-98670

In the Linux kernel, the following vulnerability has been resolved: iio: adc: xilinx-xadc: free IRQ before cancelling the unmask worker on unbind The ZYNQ XADC alarm IRQ handler queues zynqunmaskwork via scheduledelayedwork; that work is cleared by a devm callback. Register the devm callback befo...

UBUNTU-CVE-2026-98669

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: serialize buffer teardown with mode claims Buffer-mode claims hold mlock to guarantee that the device remains in buffer mode until the claim is released.
