CVE-2026-93183

CVE-2026-93183 affects the Linux kernel 's DRM Lima GPU driver (drivers/gpu/drm). The root cause is an ordering bug: lima_vm_create() is invoked before va_start and va_end are initialized, so both are zero when passed to drm_mm_init() . When DRM_DEBUG_MM is enabled, the DRM_MM_BUG_ON check fires,...

CVE-2026-93183 drm/lima: call drm_mm_init() with a valid allocation range

In the Linux kernel, the following vulnerability has been resolved: drm/lima: call drmmminit with a valid allocation range limavmcreate is currently run before vastart and vaend are set up, meaning they are both 0. limavmcreate runs drmmminit with them as arguments for the allocator, and if...

In the Linux kernel, the following vulnerability has been resolved: bpf,lsm: Drop bpfprogfree from sleepablelsmhooks bpfprogputrcu is the callrcu callback for non-sleepable programs. securitybpfprogfree called from there fires bpfprogfree in softirq; if a sleepable LSM prog is attached to that...

CVE-2026-93173

CVE-2026-93173 affects the Linux kernel BPF LSM subsystem. When a non-sleepable BPF program is freed via __bpf_prog_put_rcu() (a call_rcu() callback), it invokes security_bpf_prog_free(), which in turn calls bpf_prog_free in softirq context. If a sleepable LSM program is attached to the sleepable...

CVE-2026-90418

CVE-2026-90418 affects the Linux kernel's nilfs2 filesystem in the function nilfs_copy_dirty_pages() , which copies dirty DAT file folios/pages to a shadow page cache. The root cause is that the 'dirty' flag of a folio/page can be cleared asynchronously after the filesystem detects metadata corru...

CVE-2026-90305

CVE-2026-90305 affects the Linux kernel on ARM when PREEMPT_RT is enabled. The root cause is that commit c6e61c06d606 enabled PREEMPT_RT on ARM without selecting HAVE_POSIX_CPU_TIMERS_TASK_WORK , leaving CPU timers to expire in hard IRQ context . On PREEMPT_RT, this causes run_posix_cpu_timers() ...
