CVE-2024-35956

CVE-2024-35956 affects the Linux kernel's btrfs quota groups handling. During subvolume create/snapshot/delete, metadata reservations are made via btrfs_subvolume_reserve_metadata(). When quotas are enabled, a PREALLOC qgroup reservation is created and later converted to PERTRANS after the operat...

CVE-2023-53084

CVE-2023-53084 – Linux kernel (drm/shmem) 손상 문제 확인 Impact: In the Linux kernel, the error path in drm_gem_shmem_mmap() could fail to drop a reference, causing a dma-buf shmem GEM object to be freed prematurely and potentially leading to a use-after-free. Affected component: drm/shmem-helper and r...

CVE-2021-47460

CVE-2021-47460 affects the ocfs2 code path in the Linux kernel. The vulnerability arises during conversion from inline inode data to extents, where the converter zeroed the entire data cluster by touching pages beyond i_size, which writeback may ignore, causing data loss after file growth. A fix ...

CVE-2023-53081

CVE-2023-53081 affects the Linux kernel’s ocfs2 function. When a buffered write fails to copy data into the page cache, ocfs2_write_end_nolock() zeroes the page and dirties it, which can leave a dirty page beyond EOF. If writeback occurs before i_size is expanded, the page can reach an inconsiste...

CVE-2021-47567

CVE-2021-47567 describes a Linux kernel vulnerability in the powerpc/32 code where a vmap stack overflow could lead to a hard lockup when the data MMU is not active. The root cause is that emergency_ctx was accessed with a virtual address during MMU inactivity; the fix uses a physical address ins...

CVE-2023-53597

CVE-2023-53597 affects the Linux kernel CIFS code: after STATUS_IO_TIMEOUTs exceed NUM_STATUS_IO_TIMEOUT, reconnection could leak mids and corrupt server->in_flight; the patch relocates the MID-return/credit handling to after decrypting the response (including transform-header paths), and expa...
