Description
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix wrong index reference in smb2_compound_op() In smb2_compound_op(), the loop that processes each command's response uses wrong indices when accessing response bufferes. This incorrect indexing leads to improper handling of command results. Also, if incorrectly computed index is greather than or equal to MAX_COMPOUND, it can cause out-of-bounds accesses.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is in the Linux kernel's SMB client, specifically in the smb2_compound_op() function. The function uses incorrect indices when processing each command's response, leading to improper handling of command results. Additionally, if the computed index is greater than or equal to MAX_COMPOUND, it can cause out-of-bounds memory accesses.


How can this vulnerability impact me? :

The vulnerability can cause improper handling of SMB command results and potentially lead to out-of-bounds memory accesses. This could result in system instability, crashes, or potentially allow an attacker to exploit the out-of-bounds access for malicious purposes.
