CVE-2026-64360

A flaw was found in the Linux kernel. The hfsbnoderead function within the HFS/HFS+ filesystem driver could return without fully initializing a buffer. This could lead to the use of uninitialized memory, potentially causing unpredictable system behavior or the disclosure of sensitive information...

UBUNTU-CVE-2026-64360

In the Linux kernel, the following vulnerability has been resolved: hfs/hfsplus: zero-initialize buffer in hfsbnoderead hfsbnoderead can return early without writing to the output buffer when isbnodeoffsetvalid fails or when checkandcorrectrequested length corrects the length to zero. Callers suc...

CVE-2026-64360

CVE-2026-64360 affecting the Linux kernel’s HFS/HFS+ code (hfs_bnode_read) was fixed by zero-initializing the output buffer at the start of hfs_bnode_read to ensure deterministic zero values across all paths. The bug allowed early returns when is_bnode_offset_valid() failed or when check_and_corr...

Linux Kernel HFS子系统栈溢出漏洞

CVE ID: CVE-2009-4020 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的fs/hfs/dir.c文件中的hfsreaddir函数存在栈溢出漏洞，特制的多级文件系统（HFS）可以在 hfsbnoderead函数的memcpy调用过程中触发这个溢出。攻击者可以提供源缓冲区和长度，目标缓冲区是固定长度的本地变量，这个变量存储在了hfsbnoderead调用程序的栈帧中（hfsreaddir）。由于在试图读取文件系统上目录时都会执行 hfsreaddir函数，因此用户试图检查任何文件系统内容时都会调用这个函数。 Linux...
