CVE-2023-54206 net/sched: flower: fix filter idr initialization

In the Linux kernel, the following vulnerability has been resolved: net/sched: flower: fix filter idr initialization The cited commit moved idr initialization too early in flchange which allows concurrent users to access the filter that is still being initialized and is in inconsistent state,...

CVE-2023-54206

The CVE is a Linux kernel issue in net/sched/flower where an idr initialization was moved too early in fl_change(), allowing a concurrently initialized filter to be accessed and potentially dereferenced. The published fix inserts a NULL pointer into idr early to allocate a handle but ensures fl_g...

CVE-2023-54204 mmc: sunplus: fix return value check of mmc_add_host()

In the Linux kernel, the following vulnerability has been resolved: mmc: sunplus: fix return value check of mmcaddhost mmcaddhost may return error, if we ignore its return value, 1. the memory allocated in mmcallochost will be leaked 2. null-ptr-deref will happen when calling mmcremovehost in...

CVE-2023-54204

CVE-2023-54204 affects the Linux kernel mmc sunplus driver. The patch fixes the return value handling of mmc_add_host(); if its error is ignored, memory allocated in mmc_alloc_host() may be leaked and a NULL pointer dereference can occur in spmmc_drv_remove() when deleting a non-added device. The...

In the Linux kernel, the following vulnerability has been resolved: mmc: via-sdmmc: fix return value check of mmcaddhost mmcaddhost may return error, if we ignore its return value, it will lead two issues: 1. The memory that allocated in mmcallochost is leaked. 2. In the remove path, mmcremovehos...

CVE-2022-50842 drm/virtio: Check whether transferred 2D BO is shmem

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: Check whether transferred 2D BO is shmem Transferred 2D BO always must be a shmem BO. Add check for that to prevent NULL dereference if userspace passes a VRAM BO...

CVE-2022-50842

CVE-2022-50842 affects the Linux kernel DRM virtio path. The issue arises when transferring 2D buffer objects (BOs); a non-shmem BO (e.g., VRAM) could bypass a necessary check, potentially leading to a NULL dereference. The publicly documented fix is to validate that a transferred 2D BO is always...

CVE-2023-54196

Linux kernel ntfs3: CVE-2023-54196 fix addresses NULL pointer dereference in ni_write_inode. Root cause: during inode creation, ntfs_new_inode may allocate mi->mrec; if allocation fails, mrec is NULL, and later code path ntfs_evict_inode calls is_rec_inuse(ni->mi.mrec) leading to oops. The ...
