UBUNTU-CVE-2026-98877

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v4: Don't advertise VLPIs if no ITS is probed When accidentally setting “kvm-arm.vgicv4enable=1” on a system that has no MSI controller device tree node and GICv4, it results a panic as “gicdomain” is NULL and the...

UBUNTU-CVE-2026-98875

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/gsp: add SEC2 to GA100 chip table The booter-load and booter-unload firmware run on the SEC2 falcon. During tu102gsponeinit, the booter constructor needs device-sec2 to access the SEC2 falcon. Without the .sec2 entry,...

CVE-2026-98899

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: mark the rcu locked areas properly When we bump the uref counter, there's no need to keep the rcu lock because the referred hash table can't disappear. Also, from the same reason in mtypegc we need the rcu lock...

UBUNTU-CVE-2026-98885

In the Linux kernel, the following vulnerability has been resolved: ima: return error early if file xattr cannot be changed During early boot, the filesystem is read-only and any changes to xattrs are not allowed. This fails in case of ext4 because changing xattr starts an ext4 transaction which...

UBUNTU-CVE-2026-98874

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: don't WARN on WoWLAN suspend w/o netdetect Clearly, from a user perspective, it must be valid to configure WoWLAN and then suspend while not connected to a network. Since mac80211 doesn't distinguish these cas...

UBUNTU-CVE-2026-98878

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v5: Immediately exec priority drop following activate With GICv5 an interrupt of equal or lower priority cannot be signalled until there has been a priority drop. This is done via the GIC CDEOI system instruction. Onc...

UBUNTU-CVE-2026-98896

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Keep the domain reference while processing hotplug We process hotplug events in a workqueue that may run after the domain has been removed by tbdomainremove. For example if user unloads the driver while at the same...

UBUNTU-CVE-2026-98872

In the Linux kernel, the following vulnerability has been resolved: freevxfs: don't BUG on unknown typed-extent type vxfsbmaptyped handles four typed-extent types and calls BUG in its default case, so an on-disk typed extent with any other type value crashes the kernel. It is reachable from...

CVE-2026-98915

In the Linux kernel, the following vulnerability has been resolved: media: video-i2c: use vb2videounregisterdevice on driver removal The driver uses vb2foprelease as its file release operation, so vb2videounregisterdevice should be used instead of videounregisterdevice during driver removal. This...

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Fix possible deadlock in SEV init failure path sevplatforminithandleinitexpath calls rmpmarkpagesfirmware with locked=false while the parent function of initexpath already acquired the sevcmdmutex. In the case of an...

UBUNTU-CVE-2026-98884

In the Linux kernel, the following vulnerability has been resolved: mmc: core: Add validation for host-provided maxsegs The maxsegs field is of type unsigned short, and if a host driver sets an excessively large value, it may be truncated to zero. This can cause mmcallocsg to call kmallocobjs wit...
