CVE-2026-35233

N/A

An unprivileged attacker can craft a user-space process with a malicious ELF binary containing an out-of-range sh_link field. When root-level dtrace attaches to -- or instruments -- that process (via dtrace -p , pid probes, or USDT), the ELF parser reads heap memory beyond the allocated section cache array without any bounds check. This results in an uninitialized/out-of-bounds heap read that can cause a NULL pointer dereference crash of the dtrace process (DoS), or -- depending on heap layout -- a read-then-use of a garbage pointer controlled by adjacent allocations, providing a foothold toward further exploitation in a privileged context.

Oracle Linux 缓冲区错误漏洞

Oracle Linux是美国甲骨文（Oracle）公司的一个开放且完整的操作环境，提供虚拟化、管理和云原生计算工具以及操作系统。 Oracle Linux存在缓冲区错误漏洞，该漏洞源于ELF解析器在读取超出分配段缓存数组的堆内存时未进行边界检查，可能导致未初始化或越界堆读取，进而造成空指针取消引用崩溃或利用垃圾指针进行进一步利用。以下版本受到影响：所有版本。
