In the Linux kernel, the following vulnerability has been resolved: block: skip syncblockdev on surprise removal in bdevmarkdead bdevmarkdead's @surprise == true means the device is already gone. The filesystem callback fsbdevmarkdead honours this and skips syncfilesystem, but the bare block devi...

UBUNTU-CVE-2026-64472

In the Linux kernel, the following vulnerability has been resolved: vfio/mlx5: Fix racy bitfields and tighten struct layout Bitfield operations are not atomic, they use a read-modify-write pattern, therefore we should be careful not to pack bitfields that can be concurrently updated into the same...

CVE-2026-64502

CVE-2026-64502 affects the Linux kernel IIO ADC driver (ad_sigma_delta) for devices with has_registers = false and optional rdy_gpiod. The underlying issue was in ad_sigma_delta_clear_pending_event(): reading the status path could consume a pending conversion data, corrupt the stream, and, with n...

CVE-2026-64496

The CVE-2026-64496 issue affects the Linux kernel IIO event (iio: event) where a race between kfifo_to_user and kfifo_reset_out could lead to an out-of-bounds read and leakage of kernel memory to userspace. Root cause: iio_event_getfd() uses anon_inode_getfd() to allocate and install a new FD, th...
