CVE-2022-48921

Summary of CVE-2022-48921 : In the Linux kernel, a race between sched_post_fork() and setpriority(PRIO_PGRP) for a thread group can trigger a NULL pointer dereference in reweight_entity() (part of CFS). The scenario: a main process spawns multiple new threads that then call setpriority, while sch...

CVE-2021-47340

A vulnerability was found in the Linux kernel's JFS, where the diFree function could access an invalid pointer. This occurs if a certain inode structure has a null pointer, potentially leading to system crashes or unexpected behavior when the kernel tries to manage file system metadata. Mitigatio...

CVE-2023-52752

CVE-2023-52752 (Linux kernel) is backed by concrete fix details in connected docs: a use-after-free in the SMB/CIFS client code path (cifs_debug_data_proc_show) when reading /proc/fs/cifs/DebugData during mount/umount. The fix adds a check to skip SMB sessions that are tearing down (ses_status ==...

CVE-2021-47340

CVE-2021-47340 is a Linux kernel vulnerability in the JFS subsystem. The issue arises when diFree() processes an inode without a valid ipimap, causing a NULL dereference via JFS_IP(ipimap) and leading to a GFP-related fault. The fix prevents passing an inode with IPIMAP == NULL to diFree, avoidin...
