Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： remoteproc：修复 rsc_table_for_each_entry() 中由有符号偏移导致的越界读取 是来自固件的 值，但此前被存入有符号 类型。一个经过构造的偏移量（例如 ）会被解释为 -16，导致表头（ ）位置位于表缓冲区之前 16 字节处。后续的 （可用空间）检查被绕过，因为该负数 在表达式 中被提升为大的 ，从而得到一个较大的正值 ，使得对 的越界读取得以未被检测到地继续执行。 修复方式： 将偏移量以 类型存储，并在进行任何指针算术运算之前，使用无符号

Vulnerability Title
remoteproc: fix OOB read via signed offset in rsc_table_for_each_entry()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: remoteproc: fix OOB read via signed offset in rsc_table_for_each_entry() table->offset[i] is a u32 from firmware, but was stored into a signed int. A crafted offset like 0xFFFFFFF0 becomes -16, placing hdr 16 bytes before the table buffer. The subsequent avail check was bypassed because the negative int was promoted to a large size_t in the expression "table_sz - offset - sizeof(*hdr)", yielding a large positive avail and letting the out-of-bounds hdr->type read proceed undetected. Store the offset as u32 and validate it with unsigned comparisons before any pointer arithmetic.
