CVE-2026-90208

CVE-2026-90208 affects the Linux kernel's Samsung PWM clocksource driver (clocksource/drivers/samsung_pwm). On legacy systems where the Samsung PWM timer serves as a clock source, the samsung_pwm_lock regular spinlock is converted to a sleeping (mutex-based) lock when PREEMPT_RT is enabled on ARM...

CVE-2026-90207

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: midi: Serialize input teardown with eventinput sndmidiinputevent must not be running while a rawmidi substream is closing, since this can lead to the trigger state becoming out-of-step through this sequence in...

CVE-2026-90206

CVE-2026-90206 is a race condition in the Linux kernel's nvmet (NVM Express Target) subsystem. The function nvmet_alloc_ctrl() allocates queue memory based on the subsystem's current max_qid , but a concurrent write via configfs can increase max_qid before the new controller is added to the subsy...

CVE-2026-90207

CVE-2026-90207 is a race condition in the Linux kernel ALSA seq midi subsystem (snd_seq_midi). During input teardown, snd_midi_input_event() can still execute while a rawmidi substream is closing, causing the trigger state to become out-of-step. After rawmidi_release_priv() sets rfile->rmidi t...

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: midi: Serialize input teardown with eventinput sndmidiinputevent must not be running while a rawmidi substream is closing, since this can lead to the trigger state becoming out-of-step through this sequence in...

CVE-2026-90206 nvmet: fix max_qid race between configfs and controller allocation

In the Linux kernel, the following vulnerability has been resolved: nvmet: fix maxqid race between configfs and controller allocation The function nvmetsubsysattrqidmaxstore can race against nvmetallocctrl when a subsystem's maxqid limit is modified. Suppose maxqid is currently 64. If...

CVE-2026-90205 ocfs2: validate orphan slot during inode read

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate orphan slot during inode read Patch series "ocfs2: validate active orphan slots during inode read". OCFS2 trusts active ordinary and append-DIO orphan slots read from dinodes. A corrupted slot can therefore index...

CVE-2026-90205

CVE-2026-90205 affects the Linux kernel OCFS2 filesystem . During inode read, ocfs2_validate_inode_block() validates i_suballoc_slot but leaves the active ordinary orphan slot (i_orphaned_slot) unchecked. A corrupted dinode with OCFS2_ORPHANED_FL can therefore carry a slot value outside the mount...

CVE-2026-90204

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate DIO orphan slot during inode read BUG A corrupted append-DIO dinode high byte at offset 0xa1 corrupted from 0 to 1 can carry an idioorphanedslot outside the mounted filesystem slot range and trigger a use-after-fr...

CVE-2026-90203 Squashfs: check block offset is not negative

In the Linux kernel, the following vulnerability has been resolved: Squashfs: check block offset is not negative If a negative offset is read off disk for example the offset into the decompressed fragment block, this will cause squashfscopydata to perform an out of bounds access. Fix by checking ...

CVE-2026-90204

A use-after-free vulnerability in the Linux kernel OCFS2 filesystem is triggered when a corrupted append-DIO dinode (high byte at offset 0xa1 corrupted from 0 to 1) carries an i_dio_orphaned_slot value outside the mounted filesystem's slot range. The dinode validator fails to check this active sl...
