CVE-2026-72432

Summary: CVE-2026-72432 affects the Linux kernel, specifically the tpm_crb driver. The issue arises when a device could be matched to a platform driver even if its ACPI companion is absent, due to device_match_driver_override(). Root cause: The probe path did not validate ACPI_COMPANION() for NUL...

In the Linux kernel, the following vulnerability has been resolved: rtc: msc313: fix NULL deref in shared IRQ handler at probe msc313rtcprobe calls devmrequestirq with IRQFSHARED and &pdev-dev as the cookie, but platformsetdrvdata is only called later after the clock setup. With a shared IRQ line...

CVE-2026-72406 net: sungem: fix probe error cleanup

In the Linux kernel, the following vulnerability has been resolved: net: sungem: fix probe error cleanup geminitone calls gemremoveone when registernetdev fails. gemremoveone unregisters and frees resources owned by the netdevice, including the DMA block, MMIO mapping, PCI regions, and the...

CVE-2026-72406

CVE-2026-72406 relates to the Linux kernel sungem driver. The issue occurred during probe error handling: gem_init_one() could call gem_remove_one() on register_netdev() failure and then fall through to cleanup, potentially freeing the same resources twice (DMA block, MMIO, PCI regions, net_devic...

CVE-2026-72361 drm/xe/hw_engine: Fix double-free of managed BO in error path

In the Linux kernel, the following vulnerability has been resolved: drm/xe/hwengine: Fix double-free of managed BO in error path The error path in hwengineinit explicitly frees a BO allocated with xemanagedbocreatepinmap via xebounpinmapnovm. Since the managed BO already has a devm cleanup action...

CVE-2026-72361

Summary (CVE-2026-72361) : In the Linux kernel driver path drm/xe/hw_engine, a double-free occurred for a managed buffer object (BO) in the error path of hw_engine_init(). The BO was created via xe_managed_bo_create_pin_map() and explicitly freed in the error path using xe_bo_unpin_map_no_vm(), b...
