Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from not properly initializing the old.inode quota in the ext4rename function, which could lead to memory...

CVE-2023-53294: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix null-ptr-deref on inode-iop in ntfslookup Syzbot reported a null-ptr-deref bug: ntfs3: loop0: Different NTFS' sector size 1024 and media sector size 512 ntfs3: loop0: Mark volume as dirty due to NTFS errors general...

DEBIAN-CVE-2022-50313

In the Linux kernel, the following vulnerability has been resolved: erofs: fix order = MAXORDER warning due to crafted negative isize As syzbot reported 1, the root cause is that isize field is a signed type, and negative isize is also less than EROFSBLKSIZ. As a consequence, it's handled as fast...

CVE-2022-50284

CVE-2022-50284 affects the Linux kernel (init_mqueue_fs). If setup_mq_sysctls() fails, the mqueue_inode_cachep was not released, causing a memory leak. The issue was fixed by reordering the release path in init_mqueue_fs; upstream kernel patches exist to address this, with no explicit exploit det...
