CVE-2026-90191

In the Linux kernel, the following vulnerability has been resolved: mailbox: riscv-sbi-mpxy: validate RPMI notification lengths The SBI return value controls how many bytes are copied from shared memory into the RPMI notification buffer. It is not validated against the negotiated shared-memory si...

CVE-2026-90192

In the Linux kernel, the following vulnerability has been resolved: mailbox: qcom-cpucp: handle NULL data in senddata callback mailboxclearchannel calls mboxsendmessage with NULL data to notify the remote side that the RX channel has been cleared. qcomcpucpmboxsenddata blindly dereferenced the da...

CVE-2026-90190

In the Linux kernel, the following vulnerability has been resolved: nullblk: use DEFINEMUTEX for the file-scope mutex In nullinit, mutexinit&lock currently happens after configfsregistersubsystem, which exposes the nullb subsystem to userspace. A racing mkdir into /sys/kernel/config/nullb/ can...

CVE-2026-90189

In the Linux kernel, the following vulnerability has been resolved: nullblk: register configfs subsystem after creating default devices In nullinit, configfsregistersubsystem currently runs before registerblkdev, so when nullblk is built as a module, a racing mkdir + poweron from userspace can...

CVE-2026-90188

In the Linux kernel, the following vulnerability has been resolved: nullblk: free global tagset on init error path If sharedtags is enabled, nullsetuptagset allocates the global tagset via nullinitglobaltagset. If device creation later fails, errdev destroys the default devices and calls...

CVE-2026-90186

In the Linux kernel, the following vulnerability has been resolved: nullblk: reject per-device queue resize for shared tag set When sharedtags is enabled, nullsetuptagset makes the device use the global tagset, whose driverdata stays NULL. nullmapqueues therefore falls back to the module-wide...

CVE-2026-90187

In the Linux kernel, the following vulnerability has been resolved: nullblk: free zones array on device power-off nullinitzoneddev allocates dev-zones when a zoned device is powered on, but nulldeldev never frees it on power-off; dev-zones is only freed later in nullfreedev, when the configfs...

CVE-2026-90185

In the Linux kernel, the following vulnerability has been resolved: nullblk: serialize configfs attribute stores with the lock The NULLBDEVICEATTR store takes no lock: applyfn attributes submitqueues, pollqueues get dev-NAME written again after applyfn returns, outside its lock; APPLY=NULL...

CVE-2026-90183

In the Linux kernel, the following vulnerability has been resolved: blk-iolatency: clear delay state when freeing policy data io.latency can throttle a group which has no latency target of its own. When a sibling misses its target, checkscalechange scales down its peers, and a peer that reaches...

CVE-2026-90184

In the Linux kernel, the following vulnerability has been resolved: nullblk: serialize configfs attribute updates with device setup The attribute store methods generated with NULLBDEVICEATTR refuse to change the configuration of a live device by testing NULLBDEVFLCONFIGURED, but that flag is only...

CVE-2026-90182

In the Linux kernel, the following vulnerability has been resolved: blk-iocost: clear delay state when freeing policy data iocgkickdelay turns sufficiently large debt into an explicit block-cgroup delay with blkcgsetdelay, setting blkg-usedelay to -1 and incrementing blkcg-congestioncount. Cleari...

CVE-2026-90180

In the Linux kernel, the following vulnerability has been resolved: block: mtip32xx: synchronize ioctls with device removal The ioctl handlers only test REMOVEPENDING before entering mtiphwioctl. Removal can set that bit immediately afterwards and free dd-port in mtiphwexit while an ioctl still...

CVE-2026-90181

In the Linux kernel, the following vulnerability has been resolved: ublk: avoid teardown retry loop on xarray allocation failure ublkshmemremoveranges removes matching maple tree ranges in batches, but first stores each range into a temporary xarray so that the pages can be unpinned after droppin...

CVE-2026-90179

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix deadlock in complain-mode changehat The use of changehat when in complain mode can cause a deadlock when the hat doesn't exist and a new learning profile is created for the missing profile. This is because changehat...

CVE-2026-90178

In the Linux kernel, the following vulnerability has been resolved: hwmon: coretemp Fix coredata leak on CPUs without PTS pdata-coredata is allocated in inittempdata when the first core tempdata of a package is created, but it is only released from destroytempdata, and only in the branch that...

CVE-2026-90177

In the Linux kernel, the following vulnerability has been resolved: bpf: Check pointer type for all atomic RMW paths Atomic RMW verification records an instruction pointer type only when the current destination is PTRTOARENA. A second path can therefore reach the same instruction with an ordinary...

CVE-2026-90176

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Do not skip lock checks for single-byte ranges checklockrange uses inclusive ranges. Its callers pass the end offset as start + length - 1, so start == end represents a valid single-byte range rather than an empty range. T...

CVE-2026-90174

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix slab-out-of-bounds read in ksmbdallocuser ksmbdallocuser copies resp-hashsz bytes out of the mountd IPC login response with user-passkeysz = resp-hashsz; user-passkey = kmallocresp-hashsz, KSMBDDEFAULTGFP; if...
