CVE-2026-23470

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Fix deadlock in soft reset sequence The soft reset sequence is currently executed from the threaded IRQ handler, hence it cannot call disableirq which internally waits for IRQ handlers, i.e. itself, to complete...

CVE-2026-23454

In the Linux kernel, the following vulnerability has been resolved: net: mana: fix use-after-free in manahwcdestroychannel by reordering teardown A potential race condition exists in manahwcdestroychannel where hwc-callerctx is freed before the HWC's Completion Queue CQ and Event Queue EQ are...

UBUNTU-CVE-2026-23469

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Synchronize interrupts before suspending the GPU The runtime PM suspend callback doesn't know whether the IRQ handler is in progress on a different CPU core and doesn't wait for it to finish. Depending on timing,...

CVE-2026-23469

CVE-2026-23469 concerns the Linux kernel’s drm/imagination driver, where a race between the Runtime PM suspend callback and the IRQ handler could let the IRQ thread access GPU registers while the GPU is suspended. The description in multiple sources states that synchronize_irq() should be awaited...

CVE-2026-23422

In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: Fix interrupt storm after receiving bad ifid in IRQ handler Commit 31a7a0bbeb00 "dpaa2-switch: add bounds check for ifid in IRQ handler" introduces a range check for ifid to avoid an out-of-bounds access. If an...

CVE-2026-23422

CVE-2026-23422 concerns the Linux kernel’s dpaa2-switch component. An out-of-bounds if_id detected in the IRQ handler could leave the interrupt status uncleared, potentially causing an interrupt storm and a DoS-like condition. The technical details in connected documents show the root cause as mi...
