It was discovered that the ext4 file system implementation in the Linux kernel contained a use-after-free vulnerability. An attacker could use this to construct a malicious ext4 file system image that, when mounted, could cause a denial of service system crash. CVE-2022-1184 It was discovered tha...

CVE-2023-34256

An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4groupdesccsum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend again...

USN-6013-1: Linux kernel (AWS) vulnerabilities

Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment. A remote attacker could use this to cause a denial of service connection termination or inject forged data. CVE-2020-36516 Ke Sun, Alyssa Milburn,...

A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet the kernel could be affected.
