Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

accel/rocket: fix UAF via dangling GEM handle in create_bo

rocket_ioctl_create_bo() inserts a GEM handle into the file's IDR via drm_gem_handle_create() early on, then performs several operations that can fail (sgt allocation, drm_mm insert, iommu_map). If any fail after the handle is live, the error path calls drm_gem_shmem_object_free() which kfree's the object without removing the handle from the IDR.

This leaves a dangling handle pointing to freed slab memory. Any subsequent ioctl using that handle (PREP_BO, FINI_BO, SUBMIT) calls drm_gem_object_lookup() and dereferences freed memory (UAF).

Fix by moving drm_gem_handle_create() to after all fallible operations succeed, matching the pattern used by panfrost, lima, and etnaviv.

Also fix drm_mm_insert_node_generic() whose return value was silently overwritten by iommu_map_sgtable() on the next line. Add the missing error check.

Affected: Ubuntu:26.04:LTS: linux-ibm, Ubuntu:26.04:LTS: linux-oracle

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. (CVE-2025-54518)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - x86 platform drivers; - PSP security protocol; - ARM32 architecture; - ARM64 architecture; - MIPS architecture; - PowerPC architecture; - RISC-V architecture; - S390 architecture; - User-Mode Linux (UML); - x86 architecture; - Block layer subsystem; - Cryptographic API; - Intel NPU Driver; - Compute Acceleration Framework; - ACPI drivers; - Auxiliary display drivers; - Drivers core; - DRBD Distributed Replicated Block Device drivers; - Rados block device (RBD) driver; - Ublk userspace block driver; - Compressed RAM block device driver; - Bluetooth drivers; - Bus devices; - Character device driver; - Clock framework and drivers; - CPU frequency scaling framework; - Hardware crypto device drivers; - Buffer Sharing and Synchronization framework; - DPLL subsystem; - EDAC drivers; - Arm Firmware Framework for ARMv8-A(FFA); - EFI core; - FWCTL subsystem; - GPIO subsystem; - GPU drivers; - HID subsystem; - Hardware monitoring drivers; - I2C subsystem; - I…
