CVE-2025-68191 udp_tunnel: use netdev_warn() instead of netdev_WARN()

In the Linux kernel, the following vulnerability has been resolved: udptunnel: use netdevwarn instead of netdevWARN netdevWARN uses WARN/WARNON to print a backtrace along with file and line information. In this case, udptunnelnicregister returning an error is just a failed operation, not a kernel...

CVE-2025-68191

In the Linux kernel, CVE-2025-68191 is addressed by replacing netdev_WARN() with netdev_warn() in udp_tunnel_nic_register(). The old netdev_WARN() prints a backtrace via WARN/WARN_ON, which is inappropriate for an error that is simply a normal memory-allocation failure (kzalloc() or udp_tunnel_ni...

CVE-2025-68190 drm/amdgpu/atom: Check kcalloc() for WS buffer in amdgpu_atom_execute_table_locked()

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/atom: Check kcalloc for WS buffer in amdgpuatomexecutetablelocked kcalloc may fail. When WS is non-zero and allocation fails, ectx.ws remains NULL while ectx.wssize is set, leading to a potential NULL pointer dereferen...

CVE-2025-68170 drm/radeon: Do not kfree() devres managed rdev

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Do not kfree devres managed rdev Since the allocation of the drivers main structure was changed to devmdrmdevalloc rdev is managed by devres and we shouldn't be calling kfree on it. This fixes things exploding if the...

CVE-2025-68169

CVE-2025-68169 affects the Linux kernel where a deadlock can occur in netpoll when memory allocation happens under a spinlock in refill_skbs(). Under memory pressure, refill_skbs() holds skb_pool->lock, then alloc_skb() may fail and trigger slab_out_of_memory(), leading to printk() which can i...

CVE-2025-68169 netpoll: Fix deadlock in memory allocation under spinlock

In the Linux kernel, the following vulnerability has been resolved: netpoll: Fix deadlock in memory allocation under spinlock Fix a AA deadlock in refillskbs where memory allocation while holding skbpool-lock can trigger a recursive lock acquisition attempt. The deadlock scenario occurs when the...

CVE-2025-68167 gpiolib: fix invalid pointer access in debugfs

In the Linux kernel, the following vulnerability has been resolved: gpiolib: fix invalid pointer access in debugfs If the memory allocation in gpiolibseqstart fails, the s-private field remains uninitialized and is later dereferenced without checking in gpiolibseqstop. Initialize s-private to NUL...

CVE-2025-68167

Summary (CVE-2025-68167) : In the Linux kernel gpiolib, a path in debugfs allows a local attacker to trigger a pointer dereference. The root cause is that if memory allocation in gpiolib_seq_start() fails, s->private remains uninitialized and is later dereferenced in gpiolib_seq_stop(). The fi...

In the Linux kernel, the following vulnerability has been resolved: fs: ext4: change GFPKERNEL to GFPNOFS to avoid deadlock The parent function ext4xattrinodelookupcreate already uses GFPNOFS for memory alloction, so the function ext4xattrinodecachefind should use same gfpflag...

CVE-2025-40348 slab: Avoid race on slab->obj_exts in alloc_slab_obj_exts

In the Linux kernel, the following vulnerability has been resolved: slab: Avoid race on slab-objexts in allocslabobjexts If two competing threads enter allocslabobjexts and one of them fails to allocate the object extension vector, it might override the valid slab-objexts allocated by the other...

CVE-2025-40348

CVE-2025-40348 concerns a race in the Linux kernel slab allocator. When two threads concurrently execute alloc_slab_obj_exts() and one fails to allocate the object extension vector, the winning thread may overwrite the other thread’s valid slab->obj_exts with OBJEXTS_ALLOC_FAIL, leading the ra...
