In the Linux kernel, the following vulnerability has been resolved: net: ipv4: Fix UDP length overflow with PMTU discover and big MTU This commit bounds cork-base.fragsize to IPMAXMTU to avoid a possible overflow of UDP length that triggers a WARN in udpsetlenshort when setsockopt IPMTUDISCOVER i...

CVE-2026-98393

The Linux kernel contains a vulnerability where an overflow of the UDP length field can occur when using Path MTU Discovery (PMTUD) with a large MTU. Specifically, if a network device has an MTU greater than IP_MAX_MTU + 20 and setsockopt is set to IP_PMTUDISC_PROBE, the maxnonfragsize can exceed...

CVE-2026-98392 Bluetooth: btintel_pcie: fix tx_handle bounds off-by-one

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintelpcie: fix txhandle bounds off-by-one Valid indices into txq-urbd0s/tfds/bufs are 0..txq-count-1, so tfdindex == txq-count is already out of range. Change the guard in btintelpciemsixtxhandle from ' txq-count' to...

CVE-2026-98391

The Linux kernel contains a vulnerability in the drm/xe driver where the asynchronous dropping of a VM's runtime PM reference during teardown allows a device to autosuspend while stale page faults remain queued. When the page-fault worker attempts to acknowledge these faults, it calls guc_ct_send...

EUVD-2026-101039

In the Linux kernel, the following vulnerability has been resolved: x86/amdnode: Avoid divide by zero on virtualized systems On a virtualized system, the number of nodes does not have a relationship to the number of roots. A Xen PVH dom0 can calculate rootspernode as 0, which crashes with a divid...

CVE-2026-98390 x86/amd_node: Avoid divide by zero on virtualized systems

In the Linux kernel, the following vulnerability has been resolved: x86/amdnode: Avoid divide by zero on virtualized systems On a virtualized system, the number of nodes does not have a relationship to the number of roots. A Xen PVH dom0 can calculate rootspernode as 0, which crashes with a divid...

CVE-2026-98390

The Linux kernel contains a vulnerability where a divide by zero error can occur on certain virtualized systems, specifically Xen PVH dom0 . The issue arises because the underlying topology code on Xen can result in a roots_per_node value of 0 when num_nodes is 2 and num_roots is 1. This causes a...

CVE-2026-98389

The Linux kernel contains a vulnerability in the drm/amdgpu driver where gfx idle work may invoke switch_power_profile before a GPU reset completes. This race condition leads to an assert error because register access is attempted without first releasing the GPU reset semaphore. The issue was add...

CVE-2026-98389 drm/amdgpu: skip gfx switch_power_profile during GPU reset

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: skip gfx switchpowerprofile during GPU reset During resume from GPU reset, the gfx idle work may invoke switchpowerprofile before the reset completes. This causes the following assert error because the register access...

CVE-2026-98388

The Linux kernel is affected by a regression where the do_close_on_exec() function is called while holding the exec_update_lock . Because this function can block while waiting for a filesystem reply, it creates a risk where a hung filesystem can block other codepaths using the same lock. Addition...
