CVE-2026-74380

CVE-2026-74380 involves the Linux kernel gpu: host1x path where iommu_map_sgtable() return value check was fixed. The change switches iommu_map_sgtable() to return an ssize_t and to return negative error codes instead of a size_t zero, and pin_job() now correctly handles errors (previously might ...

CVE-2026-72245

CVE-2026-72245 relates to the Linux kernel GPU host1x driver, where a reference leak could occur in host1x_device_parse_dt() after device_initialize(). The embedded struct device was freed directly via kfree(device) in the error path, bypassing normal device lifetime handling and leaking a refere...

The vulnerability of the drivers/gpu/host1x components of the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the drivers/gpu/host1x components of the Linux operating system is related to errors during the update of the link counters. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-68427

A flaw was found in the gpu: host1x component of the Linux kernel. The host1xbounpin function incorrectly dereferences a memory mapping after it has been freed, leading to a use-after-free vulnerability. This issue could allow a local attacker to cause memory corruption, potentially leading to a...
