CVE-2026-43263

In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix Null reference while testing fluster When multi instances are created/destroyed, many interrupts happens and structures for decoder are removed. "struct vpu_instance" this structure is shared for all flow in the decoder, so if the structure is not protected by lock, Null dereference could happens sometimes. IRQ Handler was spilt to two phases and Lock was added as well.

Root has patched CVE-2026-43263 in the linux package for Root:Ubuntu:24.04. Multiple fixed versions available.

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB) invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263)
