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...

In the Linux kernel, the following vulnerability has been resolved: iio: adc: sun4i-gpadc-iio: clean up on thermal zone registration failure If devmthermalofzoneregister fails, probe returns without unregistering the IIO map array or disabling runtime PM. Jump to errmap to release them...

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. Normal buffer updates take infoexistlock followed by mlock in...

UBUNTU-CVE-2026-98666

In the Linux kernel, the following vulnerability has been resolved: iio: gyro: adis16136: fix unprotected debugfs reads The serialnumber file operations are open coded and never call debugfsfileget, which debugfscreatefileunsafe requires. debugfsremoverecursive therefore does not wait for a read ...

UBUNTU-CVE-2026-98659

In the Linux kernel, the following vulnerability has been resolved: iio: pressure: rohm-bm1390: Return error when read fails The data reading function ignores the cached error value, and unconditionally returns 0. Return cached 'ret' -value after stopping the measurement so user knows if read...

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Ensure bounce buffer used for unaligned case is zeroed. iiopushtobufferswithtsunaligned leaks uninitialized heap memory to userspace if the data passed in is not a multiple of 8 bytes and the timestamp is enabled...

UBUNTU-CVE-2026-98667

In the Linux kernel, the following vulnerability has been resolved: iio: frequency: adf4377: Fully initialize clkinitdata and clkparentdata The clkinitdata structure contains several mutually-exclusive members for different methods to specify the possible parents of a clock, prompting drivers to...

UBUNTU-CVE-2026-98794

In the Linux kernel, the following vulnerability has been resolved: ipvs: filter some flags received in the backup server While the IPVS SYNC protocol is not secure by design we can still protect the backup server from messages that can wreak havoc. This commit addresses problems from received...

UBUNTU-CVE-2026-98793

In the Linux kernel, the following vulnerability has been resolved: netfilter: bpf: reject invalid NAT manipulation types As bpfctsetnatinfo is not validating the NAT manipulation type a wrong value can be passed directly to nfnatsetupinfo. This triggers the WARNON at nfnatsetupinfo and if...
