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 Linux kernel that stems from the mishandling of preallocation discards at indirect scope boundaries in the udf file system...

CVE-2022-48946: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: udf: Fix preallocation discarding at indirect extent boundary When preallocation extent is the first one in the extent block, the code would corrupt extent tree header instead. Fix the problem and use udfdeleteaext for deleting...

SUSE CVE-2023-52902

In the Linux kernel, the following vulnerability has been resolved: nommu: fix memory leak in dommap error path The preallocation of the maple tree nodes may leak if the error path to "errorjustfree" is taken. Fix this by moving the freeing of the maple tree nodes to a shared location for all err...

kernel: ext4: fix rbtree traversal bug in ext4_mb_use_preallocated

A flaw was identified in the ext4 filesystem’s block preallocation allocator in the Linux kernel. During allocation, the code traverses an rbtree of per-inode preallocations.Concurrently, the helper ext4mbdiscardgrouppreallocation can mark PAs as deleted, which may cause a naive rbtree traversal ...
